Error:Assertion failed: undefined/

Hiii, i hope you’re having a good day.
I need help, i use Google Chrome on a Macbook air and lately when i try to preview it says “Error:Assertion failed: undefined”
I’ve looked in every post of the episode forum and tried everything, but , nothing solved my problem.
So i sent 2 tickets to the Episode support and the told me twice to look in the Episode Forum, i swear i’m going crazy!!!

Is it possible you can post a screen shot of the problem?
