MuseScore AppImage crashes on launch

I have two machines, and each have several versions of the MuseScore AppImage - one is Linux Mint MATE 18.2, the other LM Cinnamon 19.2. The 18.3 machine has an AMD Radeon, the 19.2 machine has an NVIDIA GM108M. (I suspect this might be related to the graphics card and the recent Nvidia updates.)

The AppImage runs without problem on the 18.2 machine, and until today it ran without problem on the 19.2 machine. Today was the first day I have used MuseScore since the Nvidia updates. It also crashes when launched using the -w option and the -F option. Here are the versions I have tried.
MuseScore-3.0.5-x86_64.AppImage revision 58dd23d
MuseScore-3.4.2-x86_64.AppImage revision 148e43f
MuseScore-3.5.0-x86_64.AppImage revision bd1f852
MuseScoreNightly-202005041552-3.x-5eaa04f-x86_64.AppImage

Here are the error messages for 3.4.2.
