"Starting app... This should only take a few seconds. If it takes much longer, please report to us"

Audapolis doesn't get beyond the message in the title. Would you like any more information than I have supplied below?

Start by running audapolis and inspect the log at /home/crantok/.config/audapolis/audapolis/logs/1769274391524.log. The bundled entry point is /opt/audapolis/resources/server/server, which reports that GLIBC_2.38 is unavailable; determine the supported runtime or packaging change needed. Done means the packaged application starts beyond the “Starting app...” message on the affected Linux environment.
