Stuck note on input

I'm encountering an issue where entering a note triggers a "stuck key" response where the input triggers over and over again resulting in endless input of said note. I haven't found a consistent way to make the loop stop- right clicking over and over again and esc multiple times sometimes seem to work.

Anyone else encounter this and have a fix? This just started a few weeks ago, possibly around an MuseScore update, but I can't be sure.

Thank you!
