Runner 14.1.0rc1 hangs when building my project

A build which use to take 12 minutes is now timing out after two hours.

This worked perfectly fine under runner 14.0.1. Hangs in version 14.1.0rc1
Is there anyway I can force the shared runner to use 14.0.1?

I tried using a custom runner deployed in docker, I can build it but the package step now fails with trying to pull and push to the repository. I get some kind of Docker error which I think is related to DNS.

Any help would be appreciated,
Sandy.
