Above crash involves libc-2.24 which is not Buster, so it seems you test 
in some mixture of stable and testing system.

Probably helpful to know which official Debian package repository you 
primarily use, and which packages deviate from that - in any way, 
including held packages and packages from deb-multimedia.org.

Please also mention code included by other means than official Debian 
packages - e.g. self-compiled kernel, flatpak...
