Screen time timer reset stops apps from working

I have an ipad mini 4 that I use for my child's entertainment and learning. Because of this lockdown I rely on very much as I am working from home.

I have a limit where after 8pm until 9am the ipad is totally restricted. This is where the problem occurs. After 9am when the ipad is freed, you'll open any app and it will just halt on the welcome screen.

The only way around it is to restart the ipad, like a dumb windows machine.

The ipad is logged in as my child's account and I would be able to manage the screen time with my iphone.

SO What is going on? is there a way I can fix this other restarting every single morning?
