How to run old appImages in the latest Debian set up? Fresh one runs, Old one doesn't

Solution:

Immediately after importing any OGG format track, change the track’s sample format to 32-bit float.

While the problem for which this question was posted has been solved, for the sake of troubleshooting it would help me to know how to run an old AppImage without a virtualisation tool like QEMU.
