Saved toolbars throwing an error

With the most recent snapshot, my saved hotbars are not loading and is producing the error below. I have checked and there are no filled_maps to convert so idk what this is doing.

Expected Result: There should be no errors when loading saved toolbars
Actual Result: My saved toolbar isn’t loading and I can’t find a single filled_map that would cause it to break.
