To be "stuck on" something means to be unable to make progress or get past that thing. In most cases, it's caused by confusion, a failure to agree, or an inability to do something. Here, the speaker says "we've been stuck on this for an hour" to express that they have been unable to make progress for an hour. Ex: I've been stuck on this math problem for 10 minutes. Ex: Are you stuck? I can help you.
