Is there any way to solve the bug with BB-8's mission on D'Qar?

I've finished the storyline on Lego Star Wars: The Force Awakens (PS4 version, if it makes a difference), and am now mopping up the extra tasks. However, one of the BB-8 race missions on D'Qar is glitching out on me. I switch to BB-8, start the mission, and a loading screen appears (with the mission's countdown timer at the top of the screen). But the loading screen never leaves, so I can't do the mission - I wind up having to force-quit and restart the game in order to do anything else.

Here's a video demonstrating what I mean.

Is there any known workaround? Or am I just going to have to wait and hope for a patch?
