Global Site Tags Wdiget error when clicking a tag to view it: Oops! That page can’t be found.

Global Site Tags Wdiget is not working properly. When you click on some tags, it gives this error:

Oops! That page can’t be found.

For example, you get the above error when you click on a specific tag like budget' despite the site having posts that are tagged with that specific tag:

Name Description Slug Count
budget budget 9

Your help is appreciated. Thanks
