Removed libraries are reappearing automatically

Hey,

my customer has the problem that in th past synced SharePoint libraries are suddenly reappeared and now are syncing again completly out of nowhere.

Even when I unistall OneDrive, delete the registry keys under

and

several libraries starting to sync after a short time and even the deleted ones just reappearing out of nowhere. It doesn't matter if I desync them via OneDrive App settings or registry deletion.

Do you have any ideas or help in this?

Thanks and regards
