co-op screen going black

[aefee]

Trying to join my friend on smapi 4.0.3 and the screen just goes black and never loads.
here is the error if it helps:
[SMAPI] An error occurred in the overridden update loop: InvalidOperationException: Failed reading Character (Farmer) field 'Character (Farmer): friendshipData'
---> InvalidOperationException: Failed reading Friendship field 'Friendship: __instance.get_questionsAsked()'
---> InvalidOperationException: Operation is not valid due to the current state of the object.
