Okay, moving from the 6900XT to the RX580 has produced some interesting results.
First, the 580 has no issues with Windows 10. Only in Linux Mint.
Second, mint sees the GPU and does make an attempt to use it. But for whatever reason, the drivers don’t load correctly.
Third, I found an issue with the USB4 handshake on older threads here. Apparently the USB4 Chip had issues with Linux?
I started a Linux Mint support thread over on there forms, but it seems that the issues I am having may be caused my something other than Mint itself.

Does anyone here have any ideas?
