Keeps randomly downgrading to 4.3.2

Every few hours, Musescore just randomly reverts back to 4.3.2 and I cannot open files because they are saved on a newer version. I have to then download, install, and replace the updated application to use it again until the next time it downgrades. I want to say that it is triggered by closing the app or opening a score, but I've also just been working on a score and not been able to export because of the issue, which makes it seem like it is just happening without any action. Whenever I re-upgrade to 4.4.4, the application's date modified remains December 11th, the very first time I updated.
