I've installed 'vulkan mesa drivers' for a try, and then remove it.
https://linuxconfig.org/improve-your-wine-gaming-on-linux-with-dxvk
All good but since firefox don't start any more. (same for thunderbird)
All others softs are not affected (games, etc..). Error message:

ATTENTION: default value of option mesa_glthread overridden by environment.

Exiting due to channel error.

Can someone help me to understand what's happening?
I can downgrade to firefox 75, but it can't use my profile.
Re-install up to date version don't help.
I finally installed flatpack version, and manually copy my old profile to the flat one.
But it's temporary solution and I'll like to recover normal situation.
I also need to recover Thunderbird.

The problem don't come from vulkan's driver but from oibaf PPA.
So don't use this PPA.
First of all, remove PPA:

sudo ppa-purge ppa:oibaf/graphics-drivers

But it don't remove oibaf package's.
To do this,list residual packages:

 apt list | grep oibaf

Then reinstall all listed package manually via apt install forcing the version ("=version" after package name), referring to your ubuntu version https://packages.ubuntu.com/focal-updates/allpackages:

Example for ubntu20.04 today:

sudo apt install libdrm-common=2.4.107-8ubuntu1~20.04.2 libdrm-intel1=2.4.107-8ubuntu1~20.04.2 libdrm2=2.4.107-8ubuntu1~20.04.2 libegl-mesa0=21.2.6-0ubuntu0.1~20.04.2 libgbm1=21.2.6-0ubuntu0.1~20.04.2 libgl1-mesa-dri=21.2.6-0ubuntu0.1~20.04.2 libglapi-mesa=21.2.6-0ubuntu0.1~20.04.2 libglx-mesa0=21.2.6-0ubuntu0.1~20.04.2 libva-drm2=2.7.0-2 libva-wayland2=2.7.0-2 libva-x11-2=2.7.0-2 libva2=2.7.0-2

If some listed package don't exist in your ubuntu version, just purge it, ex:

sudo apt purge libllvm14*

Now system is back to previous state and runs normally.
