When I try to open a score that I got from a PDF conversion MuseScore just crashes, on every PC that I try to use.
I'm using Musescore 3.0.1 on Windows 10
I'm attaching the mscz file

Priority ⇒ P0 - Critical

Confirmed. Looks like the file contains a bunch of completely empty measures - not even rests - so you weren't going to get much of value from the file anyhow, but we shouldn't crash, either.

That score still crashes in 3.3.4 and latest master (soon to be 3.4) with almost the same stack trace
