Attempt to index nil with 'CurrentDataModel TypeAboutToChange'

I’m attempting to use breakpoints to step through a script when I first enter Run/Play Solo mode, and I get this error which seemingly causes Studio to freeze for a few seconds before resuming.

Repro:

  1. Create a script which runs on startup
  2. Create breakpoints within the script IDE
  3. Enter Run/Play Solo mode
  4. Observe the sabuiltin_CollisionGroupsEditor.rbxm error

Example (I suggest watching in 1080p):

I’m unable to reproduce this without the use of breakpoints in the IDE.
