Can not load the room, shows whitescreen (not even loading page) ..

[RathodDeven]

When I enter the room link in my browser, I am getting this error
Uncaught DOMException: Blocked a frame with origin "https://mydomain.com" from accessing a cross-origin frame.
I have tried this in incognito, even after clearing the cache I am getting the same error?
This error occurs only on the room links created from the specific scene, however room links from other scenes works fine. What could be reason for this and how to solve this ?
