Not sure what the root cause of my issue was, but I was able to fix my issue by doing the following:
- Uninstall Supreme Command from Steam
- delete all directories and files for Supreme Commander and Gas Powered Games
- uninstalled the faf client and deleted and directories and files for it
- uninstalled protontricks
- followed guide found at https://github.com/FAForever/faf-linux/blob/master/README.md
Created game with no issues on my Fedora 36 box. Issue resolved.
