Musescore crashing after startup on new install

I am trying to get to be able to use MuseScore on my Chromebook. I followed the installation directions from this page exactly: https://musescore.org/en/handbook/install-chromebook
Setting up the Linux install worked fine. I did have to run the given sudo lines because of missing packages, but those installed OK and I got no errors when trying to start MuseScore after that. I selected the option to have tours offered, but when I got to the first dialog box where I had to hit "Next" for the tour, the chromebook crashed and restarted. The next time I opened MuseScore I hit "Cancel" instead of "Next", thinking that maybe the problem had to do with the tour. But when I clicked on the "Create New Score" button, the chromebook crashed again and restarted. The next time, I hit cancel for the tour, cancel on the "Create New Score" window, and the chromebook crashed and restarted. So, it seems like no matter how I get to the main application window, when I do, the chromebook crashes. It is not caused by any specific score, because I haven't gotten to the point of even creating a blank score. Oh, and when I launch MuseScore again, after a crash, it asks me whether I want to restore the previous session or not. No matter whether I choose to restore or not, the application crashes. I am on a chromebook with an Intel processor, and I just installed Linux to be able to use MuseScore, I haven't done anything to configure it any differently except install the two packages needed for MuseScore and listed on the https://musescore.org/en/handbook/install-chromebook page. From another forum post, it sounded like it might be relevant what linux version, so I checked, and it is "buster".
