windeployqt does not support our prebuild kit msvc19_arm64. It is not build for the kit as the kit is cross-compiled on Windows, and the msvc19_64 kit's windeployqt with --qmake parameter does not generate a working package that can be launched on arm based Windows machine. (As mentioned here: https://bugreports.qt.io/browse/QTBUG-85820?focusedCommentId=527721&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-527721)

The issue on launching the deployed package on ARM is:

0xc00007b “the application was unable to start correctly”
