Without any info about the actual document nobody can tell you much. From color management issues to some content needing to be flattened/ rasterized manually this could be anything.
What are the file and folder names?
Can you make them using only standard letters?
What happens when you outline the text? Does it get better?

Saving and exporting other files works?
Can you try and reset the preferences? Rename the folder because then you can revert to the old preferences if it doesn't work. https://helpx.adobe.com/illustrator/using/setting-preferences.html
