How to fix error in my JS Project made by a Chrome Externsion Liner?

In my new Hangman App (making by course from Andrew J. Mead), the console tab has a error:

POST https://customer.iad-03.braze.com/api/v3/data/ net::ERR_BLOCKED_BY_CLIENT        liner-core.be.js:1

I dug down and clicked on the liner-core.be.js:1 link and it was a JS file. Here is the link because the code is too long to copy paste.

Mega Link

I tried to Ctrl + A delete the file but it came back. I don’t want to remove the extension as it is really good.

Thanks
