javascript - jQuery Ajax error: 'null' has been blocked by CORS policy

I have to make a game, which gives the definition of a word and you have to guess it. It gives me an error while making an Ajax request:

jquery-3.2.1.js:9566 Access to XMLHttpRequest at 'file:///D:/Grado%20Superior/2do/DWEC/logogrifo_CristinaBorrego/logogrifo.json' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
