perhaps try in safe mode? or create another admin user account and (whilst logged out of your main account) use the new admin account to delete this folder using the same instructions as above?
i think the issue is the fact that the folder no longer exists, but still shows .... if you cannot re-create it and then delete it, the only option really left is a windows cleanup/ 3rd party program that gets rid of broken links and folders.
although i really do not suggest you try this method below, it will erradicate almost anything, hence use extreme caution and check for spelling mistakes -
open ms dos (cmd.exe) as admin
type: rd C:\Users\Abc\Desktop\wetw /s
rmdir instead of rd maybe required depending on windows os
