@Herminio-Salgado Try the following things:

Run as administrator with a right click on the program icon. If this doesn't work you may need to deactivate Smart App Control in the Windows 11 settings. If the program still doesn't work you can also try to go into the program directory and to open the file MxQt.cfg with a texteditor.
Change

[QtOpenGlEngine]
QT_OPENGL=angle

to

[QtOpenGlEngine]
QT_OPENGL=software

If there are #-characters at the beginning of these lines, remove them.
