Illustrator freezes when "saving as"

I recently bought a new MacBookPro (running on Monterey 12.3) and installed Adobe Creative Cloud on it. Since then Illustrator keeps crashing when I try to save a file in another location or another format than the current one. Whenever I select ‘Save As’ the window comes up, but the Save button is grayed out and I can’t select anything in the window – except for ‘Save Cloud document’, that works. But I don’t want that, I want to save the file on my computer! If I don’t save as cloud document and then click ‘Cancel’, my only option is to force quit Illustrator.

In Preferences I have tried selecting ‘On your computer’ as my default file location and also unticked ‘Automatically Save Cloud Documents Every x Minutes’. I have also reset preferences and unstilled and reinstalled Illustrator, but nothing works.

Any help would be appreciated! Thanks.
