press letter N , or note-input symbol on toolbar.
press 5 for duration
quarter-note G9's (way up above 14th ledger line) begin popping up . sometime rapidly , sometimes slo .
So , press N , press 5 , and nothing else . I watch as MScore writes its own monotonous tune at the very high
pitch of G9 . It quits when I hit spacebar twice , or esc. (sometimes.)

Definitely seems like something is sending random messages to MuseScore - perhaps a glitchy MIDI keyboard, perhaps a glitchy computer keyboard, perhaps a glitchy mouse/touchpad. In any case, it's almost certainly a hardware problem; installing a different version of MuseScore is unlikely to help.
