Experimental 2.1 on Steam deck instant crash..

[Krambepod]

I tried launching several times and it crashed back to library almost instantly after pressing large green "Play" button.

I tried setting compatibility to Steam Linux Runtime 1.0 and it worked. Then I set the compatibility back to default, and subsequent launches somehow worked even without compatibility setting.
Is it a Steam hiccup, trying to launch the wrong version of the game with Proton?

Probably a temporary hiccup, as we have been changing some things on steam recently. I cannot reproduce, and if it works great now, then all's well that ends well.

This issue seems to occur more frequently with the new update.
