Agent reports `panic: duplicate metrics collector registration attempted`

[skunert]

I am attempting to run parca-agent without any flags 0.32.0 on an ubuntu server.

After a few seconds it crashes:

./parca-agent
WARN[0000] Failed to setup gRPC connection (try 1 of 5): failed to exit idle mode: passthrough: received empty target in Build()
