I'm using a macbook pro (about 3 1/2 years old). Been using Affinity for over a year. Noticed an update about a week ago and installed it ,maybe It was available for longer but just noticed it. Now for the first time I'm running into an issue. I can't export a jpeg or png. Affinity just freezes up and won't even quit. Have to shut down the computer to turn it off.
After trying several things, here's what happened. I selected an image located in my documents and opened it with Affinity. Then made an edit and selected 'save'. It worked. Then, was able to export it as another jpg also giving it a new name. It went. Now, everything I try is working again. Can't explain why that worked but for the time being, everything is fine again.
