(K)Ubuntu 22.10 not booting (kernel OOPS) for driver >450 with eGPU

I am currently facing a problem with nvidia drivers higher than 450 on my notebook (Thinkpad X1 Yoga Gen7) running Kubuntu 22.10. I have a Nvidia 2080Ti attached as eGPU via a Razor Core X.
I install the proprietary Nvidia drivers via the driver selection in settings and the only driver version that works for me is the 450 version listed. All other higher versions won’t let me boot with the eGPU attached and instead give me a kernel oops.

Sadly as the notebook doesn’t fully boot and I can’t change to tty, I can’t run the nvidia diagnostic script.
I think the issue might be related with this issue, but I am not sure.

Help and tips are much appreciated! Thanks!

After a bit of back and forth, I managed to run nvidia-bug-report.sh when driver 515 is loaded. Hope this helps :)

Same as this, known issue:

Since you’re running Ubuntu, I guess switching to the “-open” driver in Software&Updates and setting kernel parameter
might be easiest if no bios update fixing this is available.

Amazing, this did the trick! Thank you very much for your help!
