Description
Observing this when analyzing our users' crashes in Sentry.
It's never reproduced in our testing environment, so I have no idea about step/preconditions.
Unhandled exception at 0x00007FF8A8FEF4CA (Qt6Qml.dll) in eecf0319-2dc3-4347-bee1-621ebd9a015c.dmp: 0xC0000005: Access violation writing location 0x0000000000000000.
