Bug Report Description

According to the latest stable system update from 11/17/25. Decky update is 3.2.0.
Deck always reboots on its own. When booting, a black error screen sometimes appears for a few seconds with an unexpected error and the option to disable Decky. The screen is only visible for such a short time that I cannot react. Steam Deck reboots automatically at least 4 times. Once I am in SteamOS, there is no Decky loader.

Expected Behaviour

No bootloop

SteamOS version

This update was re-released November 18th

Selected Update Channel

Decky Loader Version

I'm not sure why it happens, because in log files isn't an evident error message, but:
The problem may be in CSS Loader:

Where can I find the log files on Steam Deck? I can't find them anywhere. I'm not familiar with this.

That's the error message. I also get it when I try to open Steam in desktop mode.
