Steam cant start on GPU (appearing and disappearing white window)

[Perdos_Huesos]

I'm trying to run steam on my discrete video card. I have Lenovo loq 16aph8 with Ubuntu 22.04 LTS and nvidia-535 drivers. After running steam via ternimal or shortcut - it tries load window, but window is entirely white and appears, then closes in a loop. After digging in .steam folder, I've found logs and steamhelper-logs.txt show the following info
```

```

But I can't figure out why. The games could be started easily on GPU (like Minecraft and Project Zomboid, which I tested). So why does steam have some troubles?

If you need additional information or logs - let me know. Thanks for your help!
