Please describe your issue in as much detail as possible:

Sometimes, when I play a game on steam, steam would try to shutdown (showing the 'Shutting down" message and quitting) but without closing the game.

What's weirder, sometimes steam will launch a random window of the steam client too, for example the "Add a non-steam game" window or even the "change my email" window (yes, not in the steam client itself, in a new window), which is really weird.

This seems to happen only since I switched from an NVIDIA to an AMD GPU (but might just be a bug in newer evrsion of steam after my switch)

I did a full reinstall of Fedora 42 but the issue is still present.

here is an extract of me running steam through the command line until this happen :

This messages pops up a lot in the logs and in the dump crash file :

Assert( Assertion Failed: Error: RaiseJSException: Method call failed: SharedConnection.SubscribeToEMsg call had invalid argument (arg 0): is_array: true
 ):/data/src/steamUI/spewmanager.cpp:192

Steps for reproducing this issue:

1. Play a game
2. Wait a bit, this can take longer
3. Steam tries to shut down, open a random window but the game keep running fine
