Hi, I am Dave, I will help you with this.
That WindowsApps folder is highly protected by the system to ensure all apps/games from the Store are malware free and very hard to delete, usually the only working method to remove that is to move any other data on the drive to another drive temporarily and format the drive.
Try this method.
From the link below, follow the steps to add 'Take Ownership' to the right click menu, then use that to take ownership of the WIndowsApps folder, then boot into Safe Mode to see if you can delete that folder
