Last 3.3 AppImage doesn't run in Ubuntu Studio 19.10

Hi, Gang!!!

I use Ubuntu Studio 19.10 (64 bits Linux) and I've tried 4 times to download and open the last MuseScore 3.3 AppImage and... It doesn't run.

I have click on it a lot of times and... It seems to be the app is making something (the HDD light is on for a long time), but... NOTHING!!! It doesn't run, there is not any message, nothing!!!

What's wrong here?

Is it some known bug?

How can I workaround on this?

Blessings and Greetings from Chile!!!
