Multivalue control by Microsoft DevLabs failed to load

Hi all,

Can someone please assist me with two issues regarding Microsoft DevLabs failed to load for two products?

  1. Multivalue control by Microsoft DevLabs failed to load
  2. Microsoft Team DevLabs failed to load
    It seems to be random sometimes the extension works as expected and sometimes I encounter this error message.

The work around at the moment is to perform an iisreset on the server hosting the
Team Foundation Server 2018. Even though after performing this issreset the issue will re-occur again. I would like a permanent solution.

I have read of different forums and other people are experiencing the same issue.

Microsoft says unfortunately we don’t offer support for this extension because the publisher is Microsoft Devlabs.
