Catalina is the fist release of macOS which dropped the older display drivers, so your adapter is not leveraging the newer driver so the API calls are not complete! You need a PCI graphics board that supports Metal APIs.

So don’t take this adapter out as you still need it! Instead add in a second adapter, then plug your monitor into it.
