Game crashes on startup

Hi, SPT has been crashing on startup today. I was able to play one raid and upon exfil it gave me this error message and closed, now it does it every time I open the game.

Since the message mentions the Mossberg 590, I believe this is a consequence of a daily task that required me to hand over 20 FIR Magnum shells. The Mossberg was loaded, so I think that in handing over the shells it created some error.

I hope there's no need to start anew? Can this be fixed?

Using the profile editor to remove the Mossberg soved the issue, so this can be closed
