Windows apps not opening

[Ev214]

My brother is having an issue where his computer works fine, except he cannot open Windows related apps. He is running Windows 10. He wants to open Microsoft Store and Xbox Game Bar, however, when you click on them and try to run as an administrator, they will not open. Nothing will happen at all. Other apps work fine such as Chrome, Valorant, or any other app not associated with Microsoft. My brother did tell me that he messed with some of the settings of the Windows folder awhile ago and may have changed some of the permissions. He told me he tried to make himself “owner” or something along those lines in the permissions. Sorry if this post is kind of vague , let me know if you need more details…

He is running Windows 10 Home 19045.3324. He said he changed something in the Windows App folder. The direct path to what he changed was File Program Files>WindowsApps>Properties>Security>Advanced>Permissions. He says that he made himself “owner” so he could try to fix something on Roblox, however when he went to revert the setting he changed he thinks he missed a step and it messed up the permissions for him.

The owner of that folder and its contents needs to be TrustedInstaller, hopefully changing it back and making sure to apply it to subcontents fixes it, but it might be too far gone. You don't want to mess with those unless you know what you are doing.
