B4J Question Graphical issue. Blank and frozen screens

A few weeks ago I bought a new PC with Windows 11. Everything was perfect, no problems.
A few days or a week ago, I started having problems with B4J.

All applications freeze after two or three minutes of running, with the screens frozen, and if you open a new window, it appears blank. All new screens appear blank.
Interacting seems to speed up, but it always ends the same, after a few minutes.
The application continues to work perfectly, but without screens.
The problem occurs on 3 machines with Windows 11 that I have been able to test, and on one it does not.
On Windows 10 it always works without any problem on any machine.

I suspected some recent Windows 11 update, but apparently there is no difference between the 3 PCs on which it does not work and the one that does work.
Everything done with B4J fails. In release, in debug, with Packager, with Java 8, 11, 14. And even applications made two or three years ago.
I have also tried with Windows 11 Sandbox, and in addition to the same thing happening, not even the wysiwyg of the visual designer works anymore. It also appears always blank.

No error of any kind appears at any time.

Has anyone else encountered this problem?
Any help would be appreciated
