So before reinstalling that, I tried just fully uninstalling EUP / SUP for now since some custom stuff I downloaded into them might've been corrupted I recon.
After that when I load the LSPDFR plugin the game didn't crash and let me make a new character so I'd mark it as solved.
Or for instance is there a chance that it'll do the same after I'm done making my character and try to load LSPDFR next time I start the game?
Because I think that some of the stuff I added was binded to the accessory slots my character was wearing and the clothing pieces / vests / belts were corrupted.
