There are several possible reasons for this issue. One common cause is a corrupted or outdated mouse driver. Another possibility is that a recent Windows update may have caused compatibility issues with your mouse. It could also be a hardware malfunction or a conflict with other software on your computer.
First, try updating your mouse driver. You can do this by going to the Device Manager, finding your mouse, and selecting "Update Driver." If that doesn't work, try rolling back to a previous driver version. If the issue persists, try performing a System Restore to a point before the problem started. You can also try disconnecting and reconnecting your mouse or using a different mouse altogether.
If the issue only started after a recent Windows update, it's likely a compatibility issue. You can try rolling back to a previous version of Windows or contacting Microsoft for further assistance. You can also try updating your mouse driver or performing a System Restore.
If your cursor is visible in Safe Mode, it's likely that a third-party software or driver is causing the issue. Try disabling any recently installed software or drivers and see if that resolves the problem. You can also try booting into Safe Mode with Networking and updating your mouse driver from there.
If none of the above solutions work, it's possible that there is a hardware malfunction with your mouse. Try using a different mouse to see if the issue persists. If it does, you may need to contact a computer technician for further assistance or replace your mouse altogether.
