Sonoma 14.5 update problems (Sleep/wake and freeze)

Hello,
a few days ago I switched to 14.5 (from 14.4.1).
No problems during the update, but after some time I realized that Sleep/Wake no longer works as expected and that sometime I have some sudden freezes (usually after some hours of working and under NO load).

My installation is the one described here:


I'm using OC 1.0.0

Has anyone had similar problems?
