Target docx crashes when opening completed translation with Word 365

Hi everyone! I have been using Studio 2017 for a while now with an older Office version.

I now have  a new PC, where I installed Studio 2017 and worked with LibreOffice for a few days. I eventually decided to subscribe to Office 365 to be able to work with Word files without any problems.

The problem is the following: I translate, as usual, on SDL. Then I save the target translated document. I go on to open it, but with Word 365, and the file crashes. That is to say, I can keep it open for a few seconds, but then I get the message "Word is not responding" every time... 

I have tried disabling add-ins, but it hasn't worked. I have also uninstalled and updated Office, to no avail.

Does anyone know about an incompatibility issue between Studio 2017 and Office 365?

Thank you so much,

Lourdes
