Bug: Update Ambitus, Musescore 2.3.1 crashes

How to reproduce the bug:

Open a new document, add some notes (e.g. typing "cde").
Then add ambitus (open the palettes ("F9"), select the clef in your partiture, doubleclick on ambitus in palette ("lines")).
Now select that ambitus in your partiture and press F8 (or rightclick --> edit element) to update it. But Musescore immediatly crashes.

Didn't happen before version 2.3.1
I just updated and now I got this bug. I don't use any Plug-ins.

Using Windows 10 64bit.

I hope you can help me.
