Crashes When Deleting Measures

Hi! There are measures in my score that I cannot delete or change time signature, because as soon as I delete or change the time signature, the program crashes without completing the task. I understand the problem, and how it is expecting "x-counts" in the score and when it is deleted, the program views it as an unexpected error and crashes.

My question is, is there a way that they can actually be deleted without editing a part of my score or no? The file is attached if anybody wants to experiment or edit with it.
