issue:
If you try to open a previously saved Microsoft Word document you might get the following error message:

We're sorry. We can't open %filename% because we found a problem with its contents.

The "details" reads: No error detail available.

solutions to try:

• open the document in Mircosoft Word with the built-in "open & repair" feature
• try to open your document in the free word processing software LibreOffice
• try to open your document in Google Docs
• send your document to your Android phone
