Looks like Windows Update pushed a new driver down to the laptop during the night at some point. I also noticed the Adrenalin software is back, which is great. Corsair Albert has been really helpful as well, providing a beta driver along with a few troubleshooting steps that helped gets things going again.
Everything is now running smoothly, and with the latest update to Fortnite and DX12, everything looks great.
Seems like things are getting cleaned up. May be some issues with Windows 11 to be honest. Overall, this machine is doing great.
