Dragging end of slur/tie leads to program crash.

Hello Devloperteam of MuseScore!

First of all I want to congratulate you for your great work!!

The problem I want to report is, that the program crashes, when I want to drag an anchor of a slur. The crash appears right at the moment I drop the dragged anchor. This happens not every time I do a drag and drop, but it consistenlty will crash, after some tries. To reproduce this error, please, just take the attached file example and drag one slur anchor end, let's say do it 20 times, and the program will crash.

It seems, that issue #23399 may be related to this one.
