Warthunder crashing soon after login .. ( steam is dead , but that is a different ticket )

This looks much different than the the last vukan problem.
home/bogi/.local/share/Steam/steamapps/common/War\ Thunder/launcher
i launch ( the launcher ) which starts, (normally) i click play …

Starts , i log in via web using my steam account then it continues loading … and then

LLVM ERROR: Cannot select: 0x7fb9b4893638: v8i32 = X86ISD::CVTP2SI undef:v8i32
0x7fb9b40e69b0: v8i32 = undef
In function: draw_llvm_vs_variant

it crashes. and that’s it.
hopefully fixable

i can confirm that the crash only happens after i log in to my account, but still at the loading screen … i have no idea how to get more information. help please.
I also found this link,

same problem, no more information i can dig up

After removing steam, installing the flatpack version, re-downloading warthunder fresh in the new location ( the old one could not be used for some reason ) warthunder has been working normally, not crashing ( any more than it has been crashing before ) i am working on my keybindings and screen resolutions now

Other (i think better) solution you can find in War Thunder forum, in section “Linux Related Problems & Advice” in topic named “[Ubuntu 21.10] [Mesa 21.1.4] [Linux 5.13.9] Crash due to LLVM_ERROR”.

I cannot post links here for some reason.
