Javascript SDK 2.1.7

When using Javascript SDK 2.1.7, one side is randomly selected, which will not see and hear its interlocutor. And at the same time, there is no sequence of this failure.
2-3 times in a row, the call goes fine, and then 1-2 times one of the interlocutors does not hear or see anything, but at the same time, if you turn on “Share Screen” and turn it off immediately, the video returns, but there is no audio, and it is no longer not make it work.
And this failure occurs, at random, what is the caller, what is the receiver of the call.
The code is taken from the documentation, and nothing has been changed there

This problem is observed only on Chromium-based browsers, desktop Google Chrome, Microsoft Edge, Opera. And on mobile devices powered by Chromium
