What could be the reason Player Prefs are not saved on Linux?

I am calling Application.Quit(); to quit the game which should save the player prefs. But it only generates an empty folder in ~/.config/unity3d/ExampleCompanyName/ExampleProductName

It worked in the past on Linux and it also works in the current Windows build. I haven't tracked when exactly it stopped working. I switched from built-in to HDRP, but also did a lot of other stuff. So not sure when it happened.

Or could it be a bug? I am using 2022.1.0b13
