DLL files stopped working and I'm unable to delete folders (invalid file handle)

same problem here
for several days now, a lot of random files and folders all suddenly have errors "invalid file handle" when trying to do ANYTHING with them (like read, copy, move, delete, etc), some files the programs cannot find with error "file not found" until computer restart, then OTHER files have the same problem, then one restart later the original files have the same problem yet again

for pdf files specifically, when trying to open them in some pdf apps either nothing happens, or with other apps they show the error "not allowed"

none of these files were ever named CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, or LPT9

tried sfc /scannow already and it found nothing

did DISM /Online /Cleanup-Image /RestoreHealth too

Currently doing a chkdsk
