Hello @Meg Sketch, @sarah.andrews87,

We understand that encountering technical issues can be frustrating. We are here to help and would like to suggest trying to reset Illustrator's preferences as described in this article (https://helpx.adobe.com/illustrator/kb/troubleshoot-preference-issues.html). If you don't mind, could you please follow the steps and share your observations with us?

Also, kindly check if Illustrator also behaves this way with other files. If not, kindly share some sample files you are having trouble with (https://community.adobe.com/t5/illustrator-discussions/share-your-files-in-6-simple-steps/td-p/12967531), so we can check it on our end.

We appreciate your time and effort in helping us resolve this issue.

Thanks,

Anubhav

This JUST happened to me. I've been working in illustrator for a decade, I know how to use image trace. I know I am doing nothing wrong, but what changed? Did you solve your issue, I can't find any solutions.

What does More Info... say?

Which version of Illustrator is it?

What file format is the placed image? Or is it a pasted screenshot? Try to safe the image in a diffenrent format, place it again in Illustrator and retry the tracing.
