Docker container does not work

[ld32]

The docker container does not work:
https://github.com/pyushkevich/itksnap/blob/master/Utilities/Docker/itksnap-base/Dockerfile

First, qt 6.4 does not exist any more:
https://download.qt.io/official_releases/qt/

Second, after changing to qt 6.5, we got error:
/qt/src/qtbase-everywhere-src-6.5.1/libexec/rcc: error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directory

Please help. Thanks.
