System can only run Firefox OR a steam game, but not both

Staudey it is very possible that exactly what you described happened to me. I have done a series of recoveries on this system (probably 5 or 6 since 2021) and am embarrassed to admit I would just follow guides unquestioningly in my early days of switching to linux.

Staudey trying to run either celluloid or vkcube with the __NV_DISABLE_EXPLICIT_SYNC=1 modifier did not change the outcome. Trying to run either command resulted in the same message Segmentation fault (core dumped)

and firefox crashed with this output in the terminal:

matt@matt-solus-desktop ~ $ __NV_DISABLE_EXPLICIT_SYNC=1 firefox
ExceptionHandler::GenerateDump attempting to generate:/home/matt/.mozilla/firefox/hby54hta.default-release/minidumps/06021ed3-2c67-c5bc-6be0-59046ac5a251.dmp

This report also contains technical information about the state of the application when it crashed.

For the time being I have been using Brave for compatibility/stability reasons.

MorningCoffeeZombie I also would have thought that there would be a common dependency between all of those apps which you tested (other than glibc). I too think this must be something with the nvidia drivers but I do not know what.
I know Gnome wayland sessions have been having issues from it being mentioned on the forums, and that Budgie and Gnome share components, so I would also wonder if it has something to do with DE packages.

I just discovered something new about this issue. It appears that the vulkan driver is just flat out missing. This makes it extremely confusing that games are able to be run and the same with vkcube. But nonetheless when you check the output of inxi -G there are seemingly no vulkan drivers present

inxi -G

So this is clearly a much deeper issue

I had tried this across two kernels 6.10.9-302 and 6.10.8-301, and the same issue of the Vulkan driver not being present and affecting the behaviour of games and video rendering apps continued. Both kernels show inxi -G listing no Vulkan drivers.

So I did as @ReillyBrogan suggested in the update thread and installed the linux-lts kernel (6.6.50-254) to do more testing. However this created an entirely new set of issues with my system. After installing the lts kernel and running clr-boot-manager update I restarted my system. Selecting the lts kernel results in a black screen and the system never booting but also never throwing an error, it just sits on a blank black screen in perpetuity. But the more glaring issue is the effects this had on the current kernel. After attempting to start using the lts kernel and that not working I went to switch back to the most current kernel (6.10.9.302), but the system would no longer boot immediately throwing an initrd: device error. This error is very reminiscent of other issues involving clr-boot-manager and being unable to mount boot devices where I have run into seemingly "random" initrd errors which sometimes disappear overnight.

So as of right now I am running things off of the 6.10.8-301 kernel which is the last remaining working kernel on my system. Really not sure where to go from here or how to address such glaring issues.

Matt_Nico additionally running sudo eopkg check | grep Broken | awk '{print $4}' | xargs sudo eopkg it --reinstall to check for broken packages results in both linux-lts and linux-current being replaced. This happens no matter how many times I attempt to run the command so it appears to be replacing the broken packages with broken packages.
