Image Trace crash-after clicking on advanced

I'm having an issue with image trace. When I click on advanced, image traces crashes and shuts down. This wasn't happening two days ago with the same files.

Which version, which system?

Did you already reboot the computer?

How much RAM is installed and how large is the image? Did you add anything to the file since it last worked? Is the raster file still in the same location? Is the link working?
