I’ve not yet seen anyone post a fix or workaround.
Below is a much longer thread on the issue. Also another thread on Nvidia forum
Some folks on the Nvidia thread mention factory resets and sideloading old versions of PMS. However, others tried the same and it didn’t work.
Based on info in the threads, both Plex and Nvidia are aware of the problem and are working on it. Might give them some time to come up with a fix/workaround before going down the factory-reset rabbit hole like some people on the Nvidia boards.
