I just installed Visualize 2021 on my MacBook Pro.  I wanted to try the AMD render engine (tools, options, 3d Viewport) since my Mac has an AMD Radeon Pro 5500M.  When I restarted the software I get this message. 

I have uninstalled and re-installed a few times.  It has to do with 2021 only.  I still have 2020 installed and it works fine.  Is there a way to reset the options back to the Nvidia Ray?
