It’s probably an issue with the drivers.
You can try unloading and reloading modules.

Search the forum for
opencl rmmod

One example:

What's needed for an OpenCL accelerated darktable in Manjaro?

Don’t know if this could work on Manjaro: sudo rmmod nvidia_uvm sudo modprobe nvidia_uvm I’ll give it a try tomorrow. EDIT: This is giving me high hopes. Not elegant, but better than reboot. facing same issue on manjaro linux. the temporary fix mentioned here works.
