Hi,
Could you restart your computer? Sometimes, the uninstall process doesn’t fully complete until after a reboot. Give it a try and check if the storage changes.
Secondly, Manual Deletion-
Navigate to the C:\Users\Username\AppData\Local\Packages directory. Replace the Username with your actual username. Look for any folders related to the uninstalled apps and delete them manually.
