Project crashes when I try to open the corkboard as labels

I have a large project. I opened it in the corkboard and have the index cards. Then I click on the bottom to show it as labels. It immediately crashes Scrivener entirely and sends me to the desktop.

Labels work for other projects.

I have tried deleting the UI files in settings, but that doesn’t fix the problem.

From what I understand, using labels will let me place my scene cards on different colored lines. I have multiple storylines going and I want to see them chronologically for each storyline.
