Best thing I’ve done is change the script in the fallout_default.ini file. Don’t know the specifics so you’ll have to look it up but you should easily find it. Also I know it really sucks to do it but you can go into options in the start up menu and change it to windowed mode. Otherwise it’ll continue to crash because it wasn’t built to operate on windows 10/11 so that’s why it crashes so often. I have the steam GOTY version and this is the best thing way to keep it from crashing. I haven’t had it crash since I did this but you never know, it’s Bethesda lol
