Sadly the backtrace is not helpful, debug symbols are missing.
I can also not reproduce this with the official version from http://ardour.org/download.html or https://nightly.ardour.org/

So this is either a distro-specific issue (maybe liblo or some other lib) or perhaps related to gcc-10.
You'll need a debug-build to help track this down. If your distro cannot provide one, perhaps check if the current nighly also has this issue (freebie/demo is fine, and can be installed in parallel to distro versions).

Should be more helpful this time hopefully as I figured out some stuff ;)

Your core dump seems to indicate you have Ardour-6.2.212
The actual fix is in Ardour-6.2-213-g87f7dcc5f6
I should have specified that rather than the commit.
