I have just installed the latest version of Photoshop through Creative Cloud and I can't do a single thing without this error coming up. When I press a key I just get more of the same window cascading down the screen.
I'm on a Mac running Big Sur 11.6.1.
I can't even change any settings because this error will come up almost straight away.
I have trashed preferences, completely uninstalled and re-installed. I've read the many different fixes for this error that other people have used, but I just can't even get into the settings to try those fixes. At one point I was able to see the settings menus but as soon as I click on anything it just crashes. I have granted full disk access to Photoshop...I'm out of ideas!
