AMD & Nvidia GPU Hybrid System unable to use dedicated GPU

Thanks everyone for giving me new input, I really appreciate your support!

I seem to have both mhwd-nvidia 570.133.07-2 and nvidia-550xx-dkms 550.144.03-1 on my system. Installing prime-run via sudo pacman -S nvidia-prime worked out fine. Running DaVinci Resolve with prime-run succesfully starts the program, but it crashes due to being unable to use the nvidia GPU:

GPU Initialization Failed 
DaVinci Resolve could not initialize OpenGL. Please ensure that the latest graphics drivers are installed

Since the 550xx driver and utils doesn’t seem to function I removed them and instead installed the newest drivers supporting the prime-run function: Successfully installed video-hybrid-amd-nvidia-prime:

mhwd -li

Warning: No installed USB configs!

I ran sudo reboot and tested if the driver was initialized successfully:

nvidia-smi

No devices were found

@soundofthunder Thanks for pointing this out - I lost the snippet in the process of resetting my system to a fresh installation and will take precautions to avoid that in the future. I made sure to look into threads with similar issues and the Stable Update 2025-03-24 from where I got my first basic knowledge as a complete beginner with Linux. Unfortunately after a week of troubleshooting I wasn’t able to resolve the issue on my own which led me here.

Updated system info as suggested by soundofthunder:
