What happened?

When windows screen saver is ended, VirtualBox Manager 7.1.12 always crashes.

How can we reproduce this?

run VirtualBox Manager.
cause screen saver to be active (e.g. lock screen or wait until screen saver kicks in)
unlock screen saver
VirtualBox Manager crashes immediately.
All VMs keep running without any problem.

based on the error report, I suspect a QT6 issue.

Each crash results in 2 identical crash reports in Windows Log, e.g.:
