Premiere Pro 23.1 performance issues after upgrading (Windows and NVIDIA)

Hi,

I don't know if it's because of an auto update or something like this, but my premiere pro become suddenly very very VERY slow.

Moving element on timeling lag, navigate on timeline lag, extend element on timeline lag, playback is impossible to work with because too much lag. Lag start when I try to just play a video without any effect on it !! Even with proxy (very low proxy), tried to check/uncheck high quality playback, tried all playback resolution, even 1/16 lag. And EVEN when I render from in to out a little part of my sequence, the line is green, BUT playback is lagging, that's not normal...

I've read on this forum to swith audio hardware input to none, this doesn't help.

CUDA is of course activated, all my footage, project and cache are on different M.2 SSD

Lumetry scope away too.

I don't know what to do. Everything works fine few days ago, but now it's impossible to work in this conditions...

PC specs :

Windows 10 Pro

AMD Ryzen 9 5900X
128 Gb RAM
RTX 3090

Thank in advance for your help !
