Hi there, something strange and rare happened today ... I’m working on a file with a lot of layers, groups, curves, Gaussian blur, etc. when one of the layers suddenly 'disappears' from the layers panel. The layer still exists in the layer panel, but the preview in the layer panel disappeared. Shortly after that, Affinity Photo crashed.
See Crash Report.
PS. Unfortunately I cannot repeat the action ... but maybe it will happen again sometime.
