UE5.3 Crashes for no reason

So, until earlier everything was going fine, and then suddenly when I clicked on play, the game crashed with this error code:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000000

I made another project with UE5.3, and everything worked there, and I noticed that when I deleted my old (for the project) DefaultEngine.ini file, it “somewhat” worked, or at least didnt crash.

This is my projects DefaultEngine.ini file that is apparently causing the crash:

Okay, so as weird as it sounds, the issue appears to be due to one of the Player Characaters??? The playing any of the levels with the BP_FirstPersonCharacter (which I modified) it crashes with the error above. However, if I change it to any other, it works fine…what?

I do not know why this is happening, as earlier this was no issue.
