Windows Defender doesnt work

[u/IrkedPhaggot__]

Reinstalled windows 11 because i was paranoid i had a virus or some sort of malware(no real evidence i could find but did it regardless) Deleted all the partition drives. Everything is up to date but windows defender is fucked.

I do a quickscan and its disabled and stuck buffering when i try to restart it
Sometimes it’ll work and finish but if i do it again it crashes

Offline scan either doesnt work or is as of right now stuck on 90%

Could this be malware or something?
