I got it working. Turns out it was a conflict with Windows 8. I ran chrome on compatibility mode for Windows 7 and it works now.
I'm having the same problem.
The chrome browser goes black after loading the initial game stinger. I've removed all extensions, enabled js, updated Windows Firewall for TCP/UDP in the range of 44700-44899.
The service works fine on TV via Chromecast and has worked on other computers (including a chromebook), but not on my laptop PC.

It gives me the same problem. On a practical level how did you manage to use chrome in compatibility mode with windows 7?
I had same problem. Disabled adblock and problem solved.
In example, in Brave I disabled uBlock origin and Brave default Shield.
I don't have uBlock installed. I removed all of my extensions and even removed all of my browser data. Sadly, no luck...
You need to turn off hardware acceleration in Chrome settings.
chrome://settings/system
