@Octavian20604 Thank you for testing out our insider builds! I was unable to reproduce the issue on my end using the current insiders dev build. However, I can see that exact error screen if I disable cookie access for that website and your screenshot indicates you have not allowed YouTube to access your cookies.
If this problem presists, please let us know and we will follow up & try to gather more details to help us debug your problem better. Thanks!
