I noticed that many people get error while upgrading organization from CRM2016 to Dynamics 365 .
There are mainly two reason for this
1. New Microsoft.Xrm dll not getting updated in GAC while installing Dynamics 365 update.
I suggest GAC it manually this DLL
2. Duplicate record create in metadata table mostly in optionset value . Find duplicate in metadata table and delete from SQL through query
