Confirmed, 3.6.2, 4.5.1 and lates development branch crash in it. Please report on GitHub, https://github.com/musescore/MuseScore/issues/new/choose

It seems to crash (in 3.x) with an index out of range in importmxmlpass1.cpp, line 1207:

            Staff* staff = il.at(pg->start)->staff(0);

Jojo: Just FYI, I can confirm that it also crashes 4.4.4.

The culprit in the .xml seems to be this:

    <part-list>
        <score-part id="P1">
            <part-name>Electric Bass(Finger)</part-name></score-part>
        <part-group type="stop" number="0"/>
        <part-group type="start" number="1"/>
        <part-group type="stop" number="1"/></part-list>

Changing to

    <part-list>
        <score-part id="P1">
            <part-name>Electric Bass(Finger)</part-name></score-part>
        <part-group type="stop" number="0"/>
        <part-group type="stop" number="1"/></part-list>

makes it load (but with a corruption warning "Measure 75, staff 1 incomplete. Expected: 65/64; Found 1958/1920)
