Shotcut crashing at end of day

Hello, all.
I’m trying to pin down the reason for the instability of my Shotcut project. The application log contains the following warning…Is it something to be worried about ? Any ideas on how to correct this problem?

QML ColorOverlay: Detected anchors on an item that is managed by a layout. This is undefined behavior; use Layout.alignment instead.

[Warning] <> QLayout: Attempting to add QLayout “” to VideoZoomScopeWidget “VideoZoom”, which already has a layout

Thanks very much for any help that you can give!
