I'm not seeing any lights on the mobo?
If this helps at all?
Yes that helps thank you.
You may as well dump out the VBIOS file for the GPU using TechPowerUp GPUz now - then you can compare the file to one from MSI Support.
Use the curved arrow next to UEFI VBIOS to dump the file out.
What do you see if you run winver?
Have you seen this thread: https://community.amd.com/thread/251460
Have you tried this Beta Driver?
Assuming you are on Windows 10 May 2020 Update:

I think you may need to file AMD Reporting form and open an email support case if you have not done so already.

Trying the beta drivers right now. That second link you posted is actually me lol. Winver came up with expected windows info, nothing out of sorts there
Beta just crashed my rig. I also just got an AMD update in Windows...hmm.
