What did you do?

Just after 2 seconds it crashed

What did you expect to happen?
Continue playing

What actually happened?

It crashes and exit from the web app

Are you planning send a PR to fix it?
No idea of what could be the problem.

Since it is a Comcast device and we do not have access to it, there is little we can do, you will have to investigate the issue, sorry!
