Hi Monsoft,
My name is Marc, thanks for participating in the Microsoft Community, I'm an Independent Advisor and I'll be glad to help you today.
Again define the time limit time for this application, you can observe the advice of this official link.

You can also visit the section >> What to do if screen time limits don't work the way you expect, in case it applies and the problem persists.
If the above instructions do not solve the problem, configure again, but this time, start Windows through a clean boot, it is an error-proof process.

Let me know if you have something else that I can help you with, I'd be happy to help.
Have a nice day
Regards,
Marc M.
