Getting this error in application using Flatpak 6.10 KDE Platform runtime:

OSError: /usr/lib/x86_64-linux-gnu/libshaderc_shared.so.1: undefined symbol: _ZTVN8spvtools5utils5TimerE

Is that a bug in runtime? The .so file is present there:

$ flatpak run --command=ldconfig org.kde.Platform//6.10 -p|awk '/\.so/ {print $1}' | grep libshaderc_shared
