Windows 11 became unuseable since 24H2 update

[zepp-fr]

When my notebook blanks screen, after twenty minutes or so being idle, I cannot use it anymore. I must hold on power button and restart.

Note that I run Ubuntu Linux as dual boot, and it's not affected.

I noticed I have this issue since 24H2 update. Nothing managed to fix this issue ever since.
