on windows 11 insider dev and can't access folders or do anything in file explorer

my computer has been acting really weird with file explorer. i can't open folders, upload files to discord, do anything in file explorer. at first it just wouldn't open but i got it to open and now it's broken as hell. i'm on windows 11 pro education insider preview (dev channel, build 26200.5562) not sure if this is just an issue with the insider build but i don't know. this issue has persisted for about 3 weeks and i can't do important work because i can't upload files or access folders. i can't even backup my pc. this is getting so annoying and to unenroll, i have to reset my entire pc. i picked release preview and got booted to dev...i should've stayed on windows 10. i've had so many issues since i moved to windows 11 like 2 months ago and keep in mind this was on stable, in windows 10 i never had these issues
