Unable to save project


#1

I’m getting the following error while saving my project. I checked for special characters in my text but I’m still not able to save the project. Anybody experienced this before and knows how to solve it?

Already solved the problem. It was because I copy-pasted text from a powerpoint directly into the experience.
