Pipeline is getting stuck in "Queued" state

[Ernesto Magana]

My pipeline is getting stuck in the "Queued" state on second step every time I try running it. 

I have other pipelines in different project that are able to run successfully.

There were some changes made to my pipeline recently, but it is to add a new step later on in the pipeline. I would expect that any issues with the pipeline itself would manifest as error messages in the logs or some sort of feedback when triggering the pipeline; I have yet to see a pipeline silently fail or get hung in the queued state.
