This can be reproduced when three finger swipe up (enters workspace overview), then do any 3 finger drag gesture where one finger is in a window. Further debug is needed to find the root cause.

If you don't trigger the crash then try opening and closing an app and trying again. I could reproduce this issue on Intel or AMD platforms, it uses xwayland by default. [Steps to reproduce] 1. Install 24.04.2 and update to latest 2. Open a terminal and run journalctl -f 3. You may need to wait a few moments for some background tasks like NetworkManager or PackageKit to finish what they're doing. The journal should be fairly quiet before proceeding. 3. Open another app 4. Perform the 3 finger swipe up gesture on touchscreen 5. See journal for gnome-shell errors like seen below. 6. If nothing happens try opening an app, closing it and try again. [Expected result] Desktop can be switched normally. [Actual result] The OS will stop at the apps menu windows, keyborad, mouse, touchpad and touchscreen could not get any respsonse, only press ESC key can restore normal.
