Hello,
Welcome to Microsoft Community.
Have you already tried doing an Online Repair of Office 2016?
If yes, then check if the issue is happening due to other reasons. Try opening Excel 2016 while in the Clean Boot mode and see if you are able to click on and use the Browse button normally.
You may restart the computer in Clean Boot mode and check and try installing the language packs.
To restart in Clean Boot follow the steps as per the following Microsoft Article:

Note: After you have finished troubleshooting, follow steps under “How to reset the computer to start as usual after troubleshooting with clean boot” in the article to boot to normal startup.
Hope the above information helps.
Thank you.
