When using both parameters --entitiestokeep and --entitiestoexlude it can happen that a NullReferenceException is thrown.
This happens when --entitiestokeep does not retain the entities that are then specified to be excluded by --entitiestoexclude. Since the entities were already removed by --entitiestokeep, the logic for --entitiestoexclude then tries to remove entities that were already removed.
Here is a sample call for a D365FO .edmx file that causes the exception:
.\EDMXTrimmer.exe --edmxfile=C:\Temp\d365fo-odata.edmx --entitiestokeep=DataManagementDefinitionGroups --entitiestoexclude=RetailReturnPolicies --verbose
EDMX Saved to file: Output.edmx
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.
