Photoshop CC 2020 crashes, won't restart until force reset of Mac
I'm on a 15-inch 2018 MacBook Pro operating Mac OS Mojave 10.14.6.
I've been having an ongoing issue with Photoshop CC 2020 where it freezes at the simplest of tasks (such as saving, moving an object etc), and the only thing I can do is force quit.
Once I've done that, the software refuses to restart - the icon just bounces up and down in the dock for eternity.
The only way I can restart it, is by first shutting down the MacBook Pro. However, after this error, that has trouble shutting down - it gets as far as the black screen and I have to forcibly hold down the power button to restart the computer.
Once it's back up, Photoshop restarts but I know that it won't be too long before I have to go through the whole process again. I'm normally encountering it at least once daily.
Up until today I thought it was only an issue with Photoshop, BUT I just experienced it with Illustrator CC 2020 as well.
I've already tried reinstalling the whole of Creative Cloud and used the CC Cleaner tool, but it clearly didn't help.
Please help! It doesn't feel good forcing the computer to shut down every time!
