2020 release wave 1 - An item with the same key has already been added

[chironh]

After installing the 2020 release wave 1, the plugin registration tool throws multiple errors when:

• opening "Assembly View"
• registering new image in "Assembly View"

I guess most of those exceptions are related to each other. I was thinking about the Dynamics update having multiple steps with the same GUID, but I wasn't able to identify the problem.

I can simulate this problem on multiple organizations/tenants.
The MS Plugin Registration Tool doesn't seem to be affected.

Unhandled Exception: System.SystemException

An item with the same key has already been added.
