Neither DW, nor CC, nor Br... in short, nothing can be launched and run

hello everyone,

in fact everything is said, or almost, in the title of this post. for several days now, no CC application launches.

as soon as I double click on one of their icons, including the CC itself, the disk usage performance climbs to 100%, then a long time later the splash screen appears as a flash, followed by the application window, but the window is, and remains, empty. It stays like this for a few minutes, then the application crashes.

It should be noted that during all this time, I can still use the machine, as well as all other applications (except CC) in a normal way. Only the CC and its applications remain inaccessible?

I searched on the web, in the Windows forums, I reinstalled CC desktop, I reset the CC preferences, I made sure that everything was up to date, OS, drivers, applications, I checked the disk, I exchanged with GPT, nothing did, or at least everything that has, or has been, proposed has been done...

hence my question, has this already happened to any of you...?
