What I Have Tried:

Verified that protoc-gen-grpc-java exists at C:\path\to\protoc-gen-grpc-java.exe.
Checked file permissions.
Confirmed protoc and protoc-gen-grpc-java are compatible versions.
Ran protoc --version to confirm it's installed correctly.
Tried using absolute paths in the command.

What you expected to happen

Expected Output:
The .java files should be generated without errors.
