Cannot run Audacity on Ubuntu 20.04.6 LTS

DISTRIB_DESCRIPTION=“Ubuntu 20.04.6 LTS”

I have tried to run Audacity in the following methods:

1. Appimage:

./audacity-linux-3.5.0-x64.AppImage
/lib/x86_64-linux-gnu/libatk-1.0.so.0
/lib/x86_64-linux-gnu/libatk-bridge-2.0.so.0
/lib/x86_64-linux-gnu/libcairo-gobject.so.2
/lib/x86_64-linux-gnu/libcairo.so.2
/lib/x86_64-linux-gnu/libgio-2.0.so.0
/lib/x86_64-linux-gnu/libglib-2.0.so.0
/lib/x86_64-linux-gnu/libgmodule-2.0.so.0
/lib/x86_64-linux-gnu/libgobject-2.0.so.0
/lib/x86_64-linux-gnu/libgthread-2.0.so.0
/lib/x86_64-linux-gnu/libjack.so.0
/lib/x86_64-linux-gnu/libpixman-1.so.0
/lib/x86_64-linux-gnu/libportaudio.so

A notification box briefly starts up, disappears then hangs.

2. Snap

snap run audacity

4. From Ubuntu
   /bin/audacity

I cannot find any other way to get this program running. Aside from upgrading the OS, I am at a loss how to get this done.

Any suggestions are welcome.

Thanks
