Random saving problem which crashes macOS Catalina
similar to the problem described in the thread above, my photoshop will stop saving a file (in most cases, to an external hard drive) at some percentage, which further prevents Finder copying files between disks/ejecting external drives (as photoshop is using them)/relaunch Finder/shutting down the computer (unless holding power button for a few secs).
My photoshop version is the lastest 20.0.6 and I'm using macOS 10.15 Catalina.
edit: Now I'm running macOS 10.15.1 and photoshop 21.0.1; the problem is still there.
