Trouble booting PopOS 21.10

[unprepar3D]

Hi,
I have trouble booting up my PopOS installation (yes I have a backup ). Worked fine this morning but after coming home I booted up my PC, entered my cryptsetup passphrase and shortly after that I saw the login-manager but after entering the pw I got stuck with a black screen. I was not able to enter a tty or do anything than hardware reset. Since then, my System doesnt get to the cryptsetup screen. After selecting Pop in grub I get stuck with a black screen. If I select recovery mode and after that "normal boot" it boots up "normal" but without the amdgpu driver but "llvmpipe (LLVM 12.0.1, 128 bits)" (taken from the "about" page of the system settings.
After removing quiet nosplash from the grub options I can see the system stopping with the following message:

fb:0 switching to amdgpu from VESA VGA

Any ideas how to approach this? Never really had big problems with ATI cards till now :/

but I am a bit hesitant about compiling from git and copying around system files from unknown tutorials

your driver has gone AWOL,

The inxi output was from the "recovery->boot normal", it states at the beginning gpu drivers are not loaded.
I'm now able to boot the 5.15.23 Kernel (pretty sure this didnt work either at the time I opened the thread) so its ok for now and I hope the installation heals itself without action in the near future
Pop OS really isn't a stable experience for me^^

So many people think it's just another distribution of Linux, when it's not, it may be based on Ubuntu, but it has been blended specifically for system 76's own equipment, so yes for many people it will work, but just as many people have problems with it

I obviously have no clue why but I just missed the Grub menu (wanted to start Windows) and accidentally booted the 5.16 kernel. Except some graphics glictches while booting it booted up normally and I'm writing on it right now. Did not do any system updates (just chromium) or anything... Sometimes its like witchcraft

The fact that it is developed for specific hardware threw me of for a longer time. Then I tested it and really like the cosmic desktop, flatpak instead of snap and more recent software. All those things are achievable on any distro, but the package Pop is giving out of the box is very nice.
