Evaluation resulted in a stack overflow and cannot continue

Hi everyone, Pretty new PBI user here. I built a dashboard about two months ago that I'm quite proud of. When I attempted to update the data in the table, I recieved the subject error. Even if I roll back to the orginal data table, the one that worked, I still get this error.

I've tried Google searching and combing this forum but I haven't found anything that applies. Please help so I don't have to start from scratch!
