When I try to save an illustrator file, the Finder window that pops up is frozen. None of the buttons are clickable. I've tried saving files with other apps, including Adobe apps like After Effects, and they can save files just fine - to the same folder even.

Currently using the latest version of Illustrator.

Things I've tried:
- Resetting Illustrator preferences
- Reinstalling Illustrator
- Versioning down Illustrator
- Deleting the com.illustrator cache folder
- Relaunching Finder
- Restarting the computer
- Starting with a fresh Illustrator file
- Opening an existing Illustrator file

Any solutions? At the moment, the app is completely unusable to me because I can't save anything.
