One channel unusable after using GitLab slack command

I have no resolution to add at this point but I can confirm the same behavior at my organization. We have two channels (one is a normal channel and the other is a direct message) that are non responsive. Same behavior in either the thick client or via a browser. When I say non-responsive I mean that all the traffic that was in the channel is not displayed and there is a "Loading..." message displayed. The existing messages are never displayed.
