I came across this upon reviewing similar support tickets for games on Stadia. Could you try these steps?
1. In Chrome (or any chromium based browser), go to
chrome://flags2. Locate "Hardware-accelerated video encode" and disable it.
3. Locate "override software rendering list" and turn that on.
4. Make sure your browser and Operative System is up to date.
5. Restart the computer.
Allegedly this worked for them. Otherwise, as Sadurian suggested,
make a support ticket to Larian Support directly.
