Please describe your issue in as much detail as possible:

Since the January 20th update, my Steam client keeps crashing in irregular intervals. Sometimes it restarts itself automatically, sometimes it doesn't. The January 28th update has not solved this problem, unfortunately.

These are the corresponding entries from /var/log/messages at the times of the crashes:

The invalid opcode part makes me think that this might be CPU related, so here's the output of lscpu and cat /proc/cpuinfo:

Steps for reproducing this issue:

  1. Start the Steam client
  2. Wait for the crash (& possibly restart)
  3. Check logs
  4. 🙁

If you need any additional information, then please just let me know.

Thanks for listening
Thomas 🙂

I've been seeing crashes too.

Journal output: https://gist.github.com/yaomtc/00e8fc1b28505146dbe235c0d826a15e

For me, Steam is likely to crash once or twice when I'm trying to get it going, but then it stays running well after that. Doesn't seem to crash once it's been up for a bit.

Yyaomtc 2025-02-22 github

Never mind, I think my crashes were related to compatibility tools. After removing SteamTinkerLaunch and XLM from the folder, neither of which I've used recently, the crashes seem to have stopped.

Yyaomtc 2025-02-23 github

Never mind again. Spoke too soon. Had another crash shortly after launch just now. I guess luck plays a big factor here??

Yyaomtc 2025-03-06 github

Though Steam is the same version as before, crashes have since stopped for me.
