Hi @jayakasadev,
I am not sure how to help unblock this PR, as I don't understand Bazel tooling. It looks like you are building the same component multiple times, and the linker is complaining.
FYI, I refactored the Bazel CI to be its own actions. (#776, #779) This makes it easier to see where the issue is coming from.
