This appeared when I try to save my project. What happened then?
Edit: It happens on one project, even if I deleted everything in the project. The project must be corrupted.
It looks like it tried to do a math problem on a string (text).
Did you save the project to your computer? If so, could you post it?
This happened recently to me when I tried to load a project.
based on how the error mentions a lua script i would assume this issue is on the backend
OK. I've renamed the project name from "Simple Chinese Dictionary" to "Simple Chinese". It works!
You didn't rename it, you saved it as a different project. The "original" project must've been broken beyond our ability to repair somehow
