Ubuntu 24.04 Steam Crashes on start

Game crashes on start (Ubuntu 24.04)
I played it a lot a few months back on the same machine. But right now after I click on the "Play" button on steam it shows "Cancel" for a half a second then goes back to "Play".

Anyone know how to solve this issue and start playing?

Steam (Flatpak)

Things I have tried:
- Verify game files integrity
- Proton Experimental
- Proton Hotfix
- Proton 10

flatpack doesnt check, and confirm coherence update...

could you check for :
-lib32 multilib
-proton ( native ?)

i am under cachys os ( with arch) and i have no troobleshoot at any time during all league POE2 !!!!!
