Can't install CUDA toolkit on Debian 11

Hi for all.

I would really appreciate if I could get any help. I tried installing toolkit and driver on Debian 11, but it keeps failing. I tried using the .deb file and also via package manager, of course I purged the previous installation before. From nvidia-smi, I keep getting that it “has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running”. My bug-report.log is attached.
It works in my Windows 11 machine.

Thanks in advance!
