after update sleep doesn't works

on my laptop TUXEDO InfinityBook Pro running** leap 15.4 **KDE Argon]( with these KDE repositries](
after the last update sleep stops to works.
how can I have sleep working again?

Given that, “Argon” is a “live” image, it may be difficult to inspect the systemd Journal –

  • Given a “live” image, the Journal will initially write to memory (just as a “normal” Linux system does at boot time) unless, you specify where the Journal shall be written to after the “live” system has booted.

Given that, there are some systemd Journal entries for the system sleep execution, is there anything in the Journal indicating why the execution of “system sleep” is failing?
