Thank you for the suggestion. 

I do not use Malwarebytes and it appears it was not an extension problem.

The original problem occurred the day after a system update. Edge appeared normal until I opened a blank tab and it was in Chinese. Edge would not translate the language on the page but I copied the text on the page and pasted it into a translator which identified it as Chinese.

After a lengthy troubleshooting process of trial and error I was finally able to resolve the problem. The steps included turning off Profile/Sync, clearing cookies and browsing data (several times), checking the Languages setting and changing it to another language and then back to English, then finally repairing Edge which disabled all extensions. During each of the steps I would try to change the blank tab language to English but it would not change. Hoping the problem would remedy itself, as another person mentioned, I enbled all of my previous extensions, logged into my home page sites and resigned my self to seeing Chinese on a new blank tab page. Still frustated, I tried changing the language to something other than English. I changed to languae to Spanish and it worked. After this success I was able to change the language back to English and all is well now.
