I haven't seen this bug anywhere else in the issue tracker.

Create a new score (I've tried this with only one to many instruments). Then delete all the measures to create an empty score. Crashes at this point.

It should just allow for an empty score.

Unstable Prerelease for Version: 3.0.0
Revision: 22af1e6

OS: Windows 10 64-bit

I cannot reproduce by now this issue with 22af1e6 / Windows10

1) I create a score for flute (filled with notes): flute 1.mscz
2) Cltr + A
3) Del

Result: as expected: empty score (no crash)

- I observe nevertheless that Ctrl + Del (after select all) doesn't work. But no crash too.

Could you precise exactly the steps (and which score) you are using?

Open the attached score in (22af1e6) / Windows 10.
Ctrl + A
Ctrl + Del
Crash

For what it's worth, I opened my up to date branch in Qt and did the same test. I still crashed and here is the stack trace.

Yes, it was the default score I used also.
I don't understand exactly why, but after a RevertToFactorySettings (same nigthly, of course), I can reproduce too, by now.
