Other than what browser you commonly use on the PC, there are so many efficient browsers to use the Google Messages for the Web application. If none of the other troubleshooting methods fixed the issue, then you may try using alternative browsers.

The steps are pretty much the same for any popular browser out there. I have described the example for the Chrome browser as I use it. If you think it may be some corrupt browser extension causing the Google Messages for Web to not work, then remove them immediately. Always, be aware of what you install on your PC browser. I have observed that their developers have abandoned the app/service midway. Some of the extensions are often faulty right from the start. Some of them may have become buggy or incompatible if you have not updated them timely. If you have installed various web extensions on the PC browser, you need to check them.
