Error appears after running the script

[JSJSJJSJSJSJSJSKKAIAIAIAKKKL]

I got an error after running the script for a few hours and I don't know if I have done something wrong. Chrome is on the latest version as seen on the image, but I don't know what the red thing means. I need help.

Not your fault.
This is a problem with the program which I've not been able to solve.
For now, just re-run the program
