Hi Everybody

Today I was very busy and did many things on my Proxmox Environment.
First I passed trough my GPU to a Virtual Machine.
Then I installed some LLM on that Virtual Machine. (Shouldnt be why Proxmox doesnt start anymore)

I tried to passtrough an audio device, but the VM wouldnt start anymore.
So I got rid of it and passed through, I think a Realtek Audio Device.

Now when I turn on my Server he boots, loads RAM and then goes black and reboots.
I managed to open a grub terminal before the loads the kernel.

My guess is that the Device I forwarded was neccesary for Proxmox to operate.
Is there any chance to safe boot or use the Grub terminal to undo my changes?
I managed to enter the terminal and to root via recovery mode.

Thank You

Edit: I was suggested to save my VMs and reinstall Proxmox
