This may be related to issue 24. They both happen on same machine.

I ran flatseal and it does have access just doesn't play nice.

I have other machines running BOINC native install with 470 driver and all is well. PCLinuxOS doesn't have a native package and not nice things to say about how much time they wasted trying to build a proper package from the code, so, like far too many Linux platforms, flatpak only option.
