Remove/Disable Chrome Extensions.

The best course of action is to disable all of your extensions because the problem is primarily caused by certain dubious extensions on your Chrome browser. Here is how to go about it:

Open Chrome and select the top-right triangular menu by clicking there.
Select More Tools > Extensions from the drop-down menu. You will see all of your extensions after doing this.
To turn an extension off, you now only need to turn the toggle next to it. Repeat these steps for further extensions.
Restart Chrome and refresh the page tab and website.

Similarly, you can eliminate some potential problematic expansions.

We advise looking up the extension’s specifications in the Chrome web store to verify the legitimacy of the extensions. Check the rankings and testimonials. Check the extension’s creator or owner’s information as well.

You can get rid of an extension if it seems broken in one of these ways:

Visit the Extensions page by following the directions above.
Select Remove by clicking on any extension.
To confirm, click Remove once again in the pop-up menu.

The path is copied and pasted into the text box: %LOCALAPPDATA%\Google\Chrome\UserData\
