[Strange line of photo after using Affinity Photo]

Hi, appreciate some help, I have been using Affinity Photo for a couple of years without issue. Since updating to most recent version I have noticed strange lines (missing pixels) on some but not all images when saved. Attached is an example. It may be worth noting that I also changed laptop between upgrades.

Images are saved as 100% jpg

Files sizes are approximately 50MB (example reduced)
