A family of Microsoft word processing software products for creating web, email, and print documents.
All Word documents make use of templates. If you haven't actively selected a template for your new document, it is based on the blank document template (= Normal.dotm).
What specific content does your template provide? Does it contain macros?
Note that since you are using SharePoint, you may want to ask in one of the TechNet forums (start at https://social.technet.microsoft.com/Forums/en-us/home).
It's not a specific template content causing the issue here, but the fact that the template a document is based on is located on OneDrive instead of being locally available (note that it does not matter whether the template is synchronized to the local OneDrive folder, as Word will always try to open the template from the OneDrive servers). Or as user "mcm_ham" put it back in October: "[...] I can reproduce by creating a new template in OneDrive then a new Word document based on the template then close and attempt to open the new word document. It only happens for me if the template is stored inside OneDrive, it works if it's stored outside OneDrive, and it doesn't matter if the created Word document is stored inside OneDrive or not for either case [...]". Also, this issue is not limited to SharePoint at all.
(For completeness sake, I experience the same issue on Windows 10 1511 with Office 365, all updates installed.)
