Photoshop: Doesn't render the interface completely and constant program errors
I have a Sony Vaio laptop i5 with Windows 10 and a dual Intel graphics/AMD Radeon 6600M and 6700M Series GPU.
I have been using Photoshop perfectly for years but a few days ago, after upgrading to Photoshop 2021, I have a series of failures that make impossible the use of the program.
Most noticeable is the interface renders only partially. I can't see the upper bar (Ps icon, menu headers and minimize, restore and close buttons). I can't also see the tabs of documents opened or the tabs of the panels, only the content.
Also I get an unespecified program error for almost every action I try.
I thought there was a problem with the graphic drivers so I downloaded the latest Catalyst drivers from AMD and also the beta Crimson drivers, but no way. I tried not using the Radeon GPU in the preferences of Photoshop and also in the Catalyst control center but no difference (or worse)
So I tried a FULL CLEAN WINDOWS 10 reinstall. So I installed Windows 10 and then Photoshop, nothing more. Now the problem is even worse. I can't open a file. I get the dialog asking me if I want to use the colour profile of the picture and then the program error. If I try to create a new document, I also get the program error. If I try to CLOSE the program, I also get the program error so I have to kill the task.
Menu headers are not visible but I can click where they are supposed to be and the menu opens. also the upper right buttons seem to be clickable despite they are not visible.
Here is a sreenshot of the error I get for almost everything and a screenshot of the start screen where you can see the empty upper bar. Unfotunately I can't get a screenshot of the program interface because I can not get there anymore.
