-- Information about the crash:
This is a new regression, always reproducible, that was not there just a few weeks/a month ago (in respect to Fedora 41 package feeds).

To reproduce:
* Connect external displays e.g. via a docking station
* Close the lid of the laptop (laptop should not go to the sleep)
* ...
* Lock the screen
* Open the lid
* Wait until the displays refresh
* Disconnect the docking station
* Wait until the laptop display refreshes
* Close the lid (put the laptop to sleep)
* ...
* Open the lid
* Unlock the lock screen
* Observe a report that KWin has crashed, taking down all applications

The crash can be reproduced every time.
