This error is usually caused by Windows Defender’s Ransomware Protection, which may block CotranslatorAI from accessing files in your Documents folder or your OneDrive folder. To fix this, you do not need to disable Windows Defender entirely. You can allow CotranslatorAI through Windows Defender by following these steps:

1. Open Windows Security (search for “Windows Security” in the Start menu).
2. Go to “Virus & threat protection”.
3. Scroll down and select “Ransomware protection”.
4. Click on “Manage ransomware protection”.
5. Under “Controlled folder access”, select “Allow an app through Controlled folder access”.
6. Click “Add an allowed app” and then choose “Browse all apps”.
7. Find CotranslatorAI’s .exe file on your computer and select it.

After these steps, CotranslatorAI should be able to access the necessary files without errors.
