I reproduced this crash on 90.0.0-beta1 while deleting bookmarks folders as well:
Steps:

• I was signed in to sync.

1. Have some bookmark folders, with bookmarks inside.
2. Delete one folder after another, not letting the snackbar disappear in between (not sure if related though).
3. Immediately after deleting the last folder, I entered in Edit mode for one of the bookmarks in the list.
