Photoshop 21 crashing when using "Save As" Big Sur

[#1]

When clicking "save as" in PS it taked a couple minutes for the finder to open and when it does it is locked up. It's been slow ever since Big Sur was installed a week ago. Downloaded the new update for PS today hoping it would correct this but no luck.
