Problems with GWX knight's cross modpack on SH3

Hello beutiful people, i wanted to ask some tips about crashes of the mod. I haven't played the game specifically with the mod in a while, i went back to it today and i had some various issues i never had before.

I had a pair of crashes in the loading screen but mot anymore

Then i had some crashes midgame or in campaign selection menu (game would freeze and and crash)

And it always (today) freezed for a minute or so the game when i selected the emblem for the uboat

I wanted to ask for help about it because i'm not good with managing files and i don't know what to do about it

I have 2 ideas on what it could be

1)corrupted files (because i had also crash issues a pair, literally 2, of times in f1 24, that is the only other game wich had issues, when entering the pitlane)

2)some viruses, my antivirus expired like a week ago but i don't think that could be it

Thanks in advance
