ReflectionUtil+ReflectionHelper -- no ahead of time (AOT) code was generated

[unitymatrix]

Protobuf Version：3.6.1 Unity3d Version: 2020.2.6 I have checked https://github.com/protocolbuffers/protobuf/issues/5422, https://github.com/protocolbuffers/protobuf/pull/4559.

There is a confusion that the error not always happens,even on the same phone ,with same apk and I have lots of class like abcConfig. hot to fix it?
