Beta Stuck in Generating Preview

First time this has happened and I don’t know what’s different. Did 7 cutters yesterday in beta, all black solid on a white background. Uploaded and created the STL like normal. Then one design was stuck in generating preview. Tried a new image after it and it worked fine. That problem image was able to create a stamp and a practice cookie, just not any cutter. Is there something I can do to my image to fix it so it works? Oh it also works fine in the normal cookiecad.

Can you please email the cutter as an attachment to Alternatively, you can email a link to the cutter that is having an issue by clicking the share button.
