Description

Error when starting Visual Studio as of most recent VS update. Warning about ActivityLog.xml. One error in the log:

Steps to recreate

Current behavior

Error message, but so far it seems to at least be partially working anyway.

Expected behavior

No error message?

Didn't catch the other bug, closing this as a dupe.
