Cloudflare browser isolation (RBI) troubleshooting

Did anyone experience problems with it?
I have a user where the RBI https://[TENANT].cloudflareaccess.com/browser/https://www.example.com/
just doesn’t load in an update Chrome browser (even in incognito mode), but does work with Edge for instance.

Here are the errors shown in the Chrome console (red).
Anyone have any ideas?
