Can you share a full log with me?

We've encountered this before - usually its caused by out of date QT. Are you able to try updating?

its caused by out of date QT. Are you able to try updating?

Unless OP is running Cura from source, no they are not able to update because QT is included in Cura and no matter what OP updates, the version of QT that comes with Cura is used.
