How to fix error error-invalid-lock-range in Windows 11

Solution Steps

1. 1 First, try to save your work and close the application that triggered the error. Then reopen the file. Sometimes the error is transient and a fresh start clears it. If the error persists, proceed to the next steps.
2. 2 Check if the file is stored on a network drive or cloud-synced folder. If so, copy the file to your local desktop and try opening it from there. Network latency or sync conflicts can cause invalid lock ranges. This isolates the issue to the storage location.
3. 3 If the file is local, run a disk check to ensure the file system is healthy. Press Windows key + X and select 'Windows Terminal (Admin)' or 'Command Prompt (Admin)'. Type 'chkdsk C: /f' (replace C: with the drive letter) and press Enter. If prompted, schedule the check for next restart and reboot. This repairs any file system corruption that might cause incorrect file sizes.
4. 4 If the error occurs in a specific application, check for updates. Go to the application's official website or use its built-in update feature. Developers often fix bugs like this in updates. For example, in Microsoft Office, go to File > Account > Update Options > Update Now.
5. 5 If the error persists, try opening the file in a different application that supports the same format. For example, if it's a text file, open it in Notepad instead of Word. This can help you recover the data. If the file is corrupted, you may need to use a file repair tool or restore from a backup.
