This only happens in the large orchestral score attached. I'm able to input notes in measures 1-119 with no issue, but when I try to input anything into measures 120-end, which are currently blank, the program crashes. This occurs using note inputs both from my computer keyboard and by clicking on the staff, and in all instruments.

Regression No ⇒ Yes
Priority ⇒ P0 - Critical

Confirmed. And not related to continuous view (which those score is in. but crashes also in page view) and repeat barlines (there are none)

I cannot reproduce in a current build. Is there a particular measure / staff / note I should be trying? I went with typing "A" a bunch of times starting in measure 119 and extended for several measures on the top staff, also trumpets, timpani, snare drum, and violins.

Musescore 3.6 Crashes altogether while starting ! I just updatet it, everything went fine until restart. Tried to download it again after uninstall. Nothing changed.

Different issue surely (see https://musescore.org/en/faq#faq-312352)
If it isn't (any of) that, share the score and the steps that lead to the crash.

If you are seeing a crash just starting up, that's different, please reboot, uninstall, and reinstall, or try the "repair" option from the installer after the reboot. The reboot is important. If you continue to see a problem just starting, please ask for help in the Support forum.

Regarding the original problem, I can reproduce with the release version, but not with a current build. The fix involving start repeats doesn't seem like it could be relevant. But there are a couple of other possibilities. I'm looking into it further, I'd like to be sure understand why 3.6 crashes but my current build does not.

Element* Segment::element(int track) const
{
    int elementsCount = static_cast<int>(_elist.size());   // elementCount contains quite a big number, 1892928134, regardless (or because?) _elist not being accessible. Maybe the optimizer is plaing dirty tricks here
    if (track < 0 || track >= elementsCount) {
        return nullptr;
    }
 
    return _elist[track];    // crashes here, elist not accessible
}
