I've just started messing around with zio-grpc (great work btw) and encountered some issues with the examples (all three).
1: A compiler error
It's caused by compiler-bridge, to fix this I had to update to Scala to 2.13.14.
Error encountered in SBT

2: ServerMain.serverLive failing silently
I noticed the Server applications were exiting immediately. To investigate this, I added the following to every main:
Which yielded the stack trace below. To fix this, I bumped grpc-netty to 1.64.0.
(There might be another issue around the fact the error wasn't originally logged.)
