The attached file was created in 2.0.3. If you try to load it in the nightly you get a crash. I have isolated the issue to any one of two measures which contain tied unison notes in different voices.

Looks like an infinite recursion, stack trace:

Looks familiar, ISTR having had that exact recursion in another issue, would need to find it again

Ah, found it, not an issue, but a topic in the forum: https://musescore.org/en/node/141421

There I wrote:
Theres a recent code change that seems to trigger that endless recursion, in 4e0b0dba
