How to fix Microsoft Word problem where I can't open/ edit my documents?

Hi @Jovana Pupovac
Thank you for reaching out to the Microsoft Q&A Forum. 

I understand how frustrating it can be when Word suddenly shows a message and you’re unable to open or edit your documents. 

To help better understand your situation, could you please share a bit more detail? 

• Does this happen with only one specific file, or with multiple files? 
• Are you seeing the issue in the Word desktop app, Word for the web, or both? 
• Which version of Word for Mac and macOS are you currently using? 

If this happens in Word for the web, you may try the following steps: 

• Clear your browser cache and cookies 
• Try using a different browser 
• Open Word in an incognito/private window to rule out any browser extensions or cached sessions that may be affecting it 

I look forward to your response. If the issue still persists, please feel free to share more details so I can assist you further.
