System.Buffers Exception within Grpc.Core #2670

Has anyone on the DEV team scene this phenomenon:

Exception thrown: 'System.MissingMethodException' in Grpc.Core.dll

It appears the exception is getting thrown within Core. Some context: Not sure if you guys are familiar with TAK.GOV products, but I wrote a WinTAK plugin that makes a gPRC connection with another application. This connection code has been working until I migrated from WinTAK 5.2 to 5.4. The 5.4 does not have a dependency to System.Buffers.
