Some datavis examples not launching on loa (Debian11.6)

Install Qt 6.7.3 (or released 6.7.2) on Debian11.6 arm64, and configure & build datavis examples. All are compiled, but some have issues when launching the executables and some are launching just fine.

Is some dependency perhaps missing on the Debian11.6 arm64 vm?
