调研方向
The issue names no source files or tests. Start by checking the SteamOS report mentioned in the issue and investigate how desktop mode launches AppImages and handles FUSE mounts, including the related issue #3015. Done means identifying the cause of the intermittent mount failure and verifying that AppImages launch after the relevant fix.

描述
I was having this issue in stable and upgraded to beta to see if it was reported and fixed. Nope.
Your system information
- Steam client version: 1793740892 (Build Date: Mon, Nov 2, 2026 2:32 PM UTC -06:00)
- SteamOS version:
VERSION_ID=3.9.5BUILD_ID=20261023.100 - Opted into Steam client beta?: Yes (but the issue occurs on stable too.)
- Opted into SteamOS beta?: Yes (but the issue occurs on stable too.)
- Have you checked for updates in Settings > System?: Yes
Please describe your issue in as much detail as possible:
As of more recent SteamOS updates, upon booting into desktop mode, you are sometimes inundated with multiple errors stating the following:
Cannot mount AppImage, please check your FUSE setup.
You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE for more information.
When the system is in this state, no AppImages can be opened. The issue persists until a reboot, but may come back after putting the device to sleep or randomly on some boots.
This issue has been reported by other users on Reddit.
This may be related to #3015.
Steps for reproducing this issue:
None. Issue occurs randomly. Symptoms include not being able to launch AppImages in Gaming mode, and seeing these notifications in Desktop mode.
Due to a bug in GitHub, I cannot upload my system report at the moment, but I have saved it ahead of time and can upload it later if necessary.
