Some history of what it does doesn't do or seem like so far.
It will load feed and eject unfired rounds perfectly.
A loaded round slides right in the chamber with no resistance or binding....doesn't feel peened from dry firing
The ejectors seem fine.
The Firing pin strikes are very strong.
Perhaps too much so ?
A fired case showing the backside of the rim and firing pin strike not sure what the backside cause is ?
A wag would be that the chamber is slightly oblong, or the chamber has a spot under where the firing pin would hit the empty chamber from dry firing? Just a guess
1. Feed. Once it's clear of the magazine apparatus, you can generally say a round has "fed".
2. Chamber. If the round makes it in to the point of allowing correct headspacing, you're there.
3. Lock. Is the gun fully in battery. NOTE: "Lock" may not accurately apply to blowback actions, so look to ability to fully chamber.
4. Fire. Successful ignition and departure of the projectile.
5. Unlock. Whatever's keeping the bolt or slide closed is undone.
6. Extract. Getting the empty clear of the barrel, NOT necessarily getting it clear of the gun.
7. Eject. The fired case is now in the wind.
8. Cock. Whatever mechanism responsible for hitting the primer gets reset.
Look at that cycle closely and consider carefully where your gun is failing. If your problem isn't obviously completely within one of those stages, it'll be in the one before or after. That'll tell you what parts need to be cleaned, adjusted, or replaced.
If you're leaving empties in the chamber, consider that you've got to grab the case hard enough to pull it out against any resistance of fouling or case deformity. Could be weak extractor springs, deformed or broken extractor, rough or dirty chamber, or simply ammo that's incompatible with the gun.
Different rounds are easiest to check first. Look at the empties and consider what's causing any damage of "that ain't right".

I believe we should stand on Ceremony. . . while our friends handcuff the sanctimonious little prick and take him away.
I'm pretty sure the chamber's been peened from dry firing.
This mark, aligned with the firing pin strike on the rim, seals the deal for me

What position is the ejector in relation to the firing pin.
Is the tip of the firing pin broken? Or ejector edge?
Since its a lever gun there could be quite a lot of force applied to the ejector. Is the lever at all difficult to open? Or close?
Could hand load a round to see if it easily chambers or sticks at the last. If so eject it and look at the case then. Should tell you if its a firing pin making the dent.
The firing pin is not hitting all the way to the edge of the rum so my vote is a broken firing pin at the striking edge
Feel for roundness at the back of the chamber with some kind of pokey? Removal of the barrel to gently deburr the hypothetically kneaded metal may be a foregone conclusion, but we'd like to determine the problem before taking that step if possible.
Diameter of brass body before and after firing it? Consistency of diameter - if the firing pin strike is 12:00 and directly across is 6:00, what's the diameter from 3:00 to 9:00? Is the brass swelling symmetrically?
Interesting that the exterior is so clean, and we've got this likely evidence of "death by dry fire". My Winchester 63 came home with a broken off firing pin tip (long, slender, tapered thing), undoubtedly due to no last-shot hold open to indicate you're done. No real fix in that system other than to count rounds. Since your rifle has a sexy short-throw action, it's likely it got not only dry fire at the end of a magazine, but also a lot of "playing around" snaps. THEN you've got the possibility of "I don't want to put this thing away with the springs cocked - CLICK!"
A bit outside my wheelhouse, but thinking in terms of firing pin travel:
There's probably an oblong hole in the firing pin and a cross pin retaining it in the bolt. Is the pin bent or the end of that hole which serves as a stop surface "wallered out"? Either of those would allow excessive forward travel.
OR. . . is the back of the chamber the designed-in stop surface?
Paths to prevention likely contained in the answers.

Have another look at the first pic showing the firing pin strike on the brass.
The top is scalloped and does not contact the full rim.
That indeed may have been caused by dry firing.
I looked for a spent 22 brass but didnt find one in my bag. But look at one from another gun you will see a sharp rectangular indent that covers the entire rim. If dry firing it will be the outer edge of the firing pin that takes the damage from striking the face. Could be 2 problems. Firing pin and chamber breach.
I would agree, dry firing damage to the chamber and firing pin. The pin doesn’t deform the rim of the case, all the way pout to the rim. The pin should be flat all the way to the top edge. The picture of the chamber seems to show a little deformation.
Presto! Chamber swage for 22lr. No cutting all hand tools. But in the end if it’s not effecting accuracy or function who cares if the case is slightly deformed, not like we gonna reload that case.
It wasn't hanging up at all on unfired rounds.
Figure just enough of a burr inside the chamber to stop extraction on the fired round.
I Took it apart and Im pretty sure I swaged it back.

Great it’s running now
Might check to see if you can find a new firing pin then it would be fully back and ready for years of use.
I did want to keep an empty to check.
Never hurts to have a spare of those for sure
I'm not sure the Firing pin has anything wrong yet.
My eyes suck though
To me, that "ding" on the end of the barrel means the FP has taken some damage.

I did want to check that....still will.
Unfortunately I forgot to take home an empty fired case.
One thing is a firing pin is hardened steel vs the chamber which is a softer steel.
So the chamber will take the damage first.
Right now it's still under review.
I'm leaning towards the firing pin is still intact/ undamaged
If it's not damaged, they sure picked a strange shape to mill the top edge of it.
It still seems to work, so it's not "terminal damage" though
hardened, could also mean "brittle", at least compared to the barrel steel
