I upgraded Photoshop to 24.6.0. Now, I can't open files whether by double-clicking or through File > Open. Nor can I close Photoshop without using CTRL+ALT+DEL. "Could not complete your request because of a program error." when I try to open files or close Photoshop.
I tried downgrading to an old version, and restarted many times, but now that's happening any time I try to open a file or close the program, in both the latest and previous version.
