"Problem with load ExtendedProperties" exception with large schema compare. (4232151)

When trying to run schema compare on two servers, choosing all tables gives the following error:

System.ApplicationException
Problem with load ExtendedProperties
Stack Trace:

The compare starts but never finishes. If just a few tables are chosen, it does not error out. Server compare seems to work without issue. Ignore extended properties is checked and it still errors out.
