Thanks!
Sorry, but not entirely a duplicate, since nobody else seems to be complaining about Unit Tests .
We acknowledge we can prevent the application from crashing by running it once with MultiTenancyEnabled = true and then turning it off, however, that doesn't help fixing all UnitTests which would still fail.
The workaround suggested above works but all Unit Tests still fail when you set MultiTenancyEnabled = false.
I added a few more details on #6857
The workaround works, but just to avoid the crash on initial the intial run. All Unit Tests still fail when you set MultiTenancyEnabled = false.
