How do I delete a corrupted folder from Windows.old?

I've recently reinstalled Windows after about two years, hoping it would help with some weird issues I encountered. However, I've been experiencing system freezes and I discovered there's a corrupted folder in my AppData's Temp folder that I can't seem to delete, no matter what I try. I've attempted several methods like deleting it normally, booting into Safe Mode, using 7zip, and even trying Ubuntu to remove it, but nothing works. I really want to get rid of it without doing a complete fresh install. What are my options?
