[Crashes when a Stitch, Stak or merge process is finalised]

Thanks for your advice.  I had previously deactivated the hardware acceleration, after reading forum posts but that made no difference.  I am running V1.9.2.  Where do I go to download the Beta version?

I have been using Panorama, Stack and Focus merge successfully for years in previous versions.   On updating to 1.9 Affinity Photo closes completely when I end any of these process e.g. by selecting "Apply".   My OS is the current version of Windows 10.
