It seems that the issue you reported is the same as the one described by this user. Could you take a look at the solution provided in that thread?

> Hey @lmtruong1512 Thanks for your feedback. G7hN3patQvakN5hjB1Lumw== After analyzing the logs, we found that the video was muted by the system due to interruption from another application, preventing the SDK from capturing any frames. This case has been improved in the latest Video SDK Web (2.2.0), which introduces a new exception type — ActiveMediaFailedCode.VideoStreamMuted (207) — to help developers handle this scenario. Thanks Vic

Thanks  
Vic
