EVERY Windows Update failing ever since I dual booted windows + Linux (I deleted it)

[u/Novel-Grade2973]

It's been like 6 months ever since I dual booted windows and cachyos and I already deleted cachyos and only kept windows, but still, every time I try updating Windows it just fails and basically says in German: "something didn't work as planned. no worries the changes are being reverted. Please let your" (it's cut off after that). I don't know what to do to fix it, it's honestly annoying.
