[abbatrombone]

I am having a similar issue. Removing steam and reinstalling did get it to work. Removing the cache did not work. rm -Rf all steam files and then reinstalling steam did also not work. (Debian 12 gnome, AMD GPU, Flatpak 1.14.4).

[Alee14]

I ended up removing the steam runtime and libraries and it was fixed

If you restrict steam permissions via flatpak make sure to allow=per-app-dev-shm, this was the issue for me
