That problem is a little bit surprising because the Go code generator is
implemented as a plugin in a separate repo, and shouldn't therefore be
affected by a protoc upgrade. Did you upgrade your Go protoc plugin at the
same time?
As a side note, sorry for the confusion but we decided not to increment the
major version from 3 to 4 yet. We published artifacts for 4.0.0-rc1 and
4.0.0-rc2 but there will not be a 4.0 release in the immediate future. We
are going to release 3.13.0 soon instead.
