Can't launch on Linux after patch on Steam - Exception: CreateDXGFactory1: Call failed

Game has been running fine since launch.

But today, an hour ago, the game crashed, and Steam immediately auto-updated and installed a new version of the game.
I also think there was a Steam update which autoinstalled.
Now when I try to launch, I get the error in subject, after about 4-8 seconds.

I've tried:
- Changing various launch parameters to force directx/vulkan
- Changing settings in the production config file to Vulkan/DirectX12
- Switching to other compatibility versions like
- Verified game files integrity in Steam
- Restarted PC, restarted Steam, reinstalled Steam, updated kernel
- Verified other games work, they do, but POE1 gives the exact same error.
- Tried different proton versions via steam, Hotfix version has worked since launch but now doesn't, neither does the others on 8.0 branch and 9.0 branch.

Specs/info:
- Debian 12 (bookworm)
- Kernel 6.6.13-1-liquorix-amd64, also tried kernel 6.12.6-1-liquorix-amd64
- X.Org version: 1.21.1.7
- xfce4-session 4.18.1 (Xfce 4.18)
- AMD Ryzen 5 7600 on X670 Aorus Elite AX
- 2x16GB Corsair Vengeance DDR5-6000 Dual Channel
- GeForce RTX 4090 - driver version 565.77

Steam updated the game again and after a lengthy shader recompile the game could launch again.
The shader recompile + 1.5GB+ patch is something that happens severel times daily btw.

POE2 won't start for me as well after the last update.
Getting the Dialog: "CreateDGIFactory1: Call failed"
