At a guess without looking at it, I suggest perhaps the firing pin is frozen in a forward position.
Complete teardown and cleaning is one solution.
And be gentle with that firing pin. Lots of solvent before removal.

As above, first guess is frozen firing pin. You'd be able to see it protruding from the front of the breech face.

If not that, then have you done a function test without ammunition?

Here is whaht I found, I had a rubber sleeve installed and the slam firing problem came after that.
the inside part of the sleeve was rubbing on the part with a red arrow, as you can see on pistol frame,,,I have remove the sleeve and went to the range with no more issues,,,,

A bit of grinding on the grip with a sanding drum in a rotory tool would give you some clearance
