PANIC Failed to create V4L2 device with id 50

I installed it through the aur. It stays that way with or without sudo. When I tried to find a solution I couldn't find a clear solution.

v4l2loopback is not installed on your system correctly. Please install it first. You can test it with the following command: sudo modprobe -r v4l2loopback

Thanks. The main problem was that linux-headers were not installed.
