Siri Only exporting Black jpeg images

MacBook Pro, I’ve been exporting images from Siri in jpeg format without any issue until today, now every image is pure black no matter what I do unless I export as a tiff format. I’ve reset all settings to default, rebooted. Same issue. Sliders on bottom right no longer stay at right and left just left. Anyone else have this issue?

Hi, for reference, the usual answer is here: Siril - FAQ
