There are many easy ways to fix the 7-Zip data error in Windows, ranging from a simple restart to PC virus scans.
Method 1: Restart 7-Zip
If you are having trouble extracting archive files, it may be because of a minor glitch in the app. Try restarting the 7-Zip application by following these steps:

Once the file has been successfully downloaded, extract it again using 7-Zip.
Method 3: Make Sure You’re Entering the Correct Password
If you are opening a password-protected file using 7-Zip, you may get a Data error when you enter the wrong password.
Make sure you’re entering the correct password by checking for any title case issues or typos. You should also contact the source of the file to confirm the password again.
