Why can't I permanently delete files from creative cloud?

[#1]

I have 30gb of files (9907 items) in my creative cloud deleted archive and I can't permanently delete them. When I try, the page freezes for a while and then when it refreshes, a little pop-up says 'successfully deleted 0 assets permanently'. Or it deletes some files but then the files reappear! I don't have time to delete almost 10,000 files one by one. How do I fix this? Please help!

I'm having the same issue, but with 85GB of files. You find a solution ever?
