Your system information

  • Steam client version (build number or date): Latest as of 24.11.2025

  • Distribution (e.g. Ubuntu): Ubuntu 25.10

  • Opted into Steam client beta?: No

  • Have you checked for system updates?: Yes

  • Steam Logs: steam-logs.tar.gz

  • GPU: Nvidia RTX 4080 Super with driver 580.95.05

  • Dumps from latest crash: dumps.tar.gz

Please describe your issue in as much detail as possible:

I am experiencing frequent crashes at seemingly random times. Sometimes I would load the client, enter big picture mode, browse through my library a little and get a complete crash. Sometimes it would crash randomly while a game is playing.

The crash whose logs and dumps I uploaded here happened when I was in-game (from big picture mode) and pressed the middle button on a controller to open the overlay. The result was that Steam crashed in the background, leaving me without controller input for the game.

I'll upload a few more crash reports, logs and dumps here as they happen.

Crash when opening game (Kingdom Come: Deliverance). Black screen with a taskbar, controller input does nothing. Mouse and keyboard work, issued alt-F4 to the black screen and manually closed the game process, which was hanging.

I will continue to update if there is interest.

@noammor , not sure if you're having a similar problem as me with the general client behavior outside of your crashes but my Steam Client is constantly restarting while playing a game.

I'll add to this. My Steam Client has started crashing and bringing down Steam Input at the same time. Sometimes I can keep playing if the game survives without the Steam Client. Other times I need a full reboot.
