Hi Gallken2020,
We understand you're unable to sign in to the App Store and iCloud. We're happy to help.
To begin, we'd suggest providing some more detail on what is happening when you try to sign in to the App Store. Are you unable to access the settings to select the sign in option? Are you able to enter your details but then get some sort of error? Etc.
Answers to questions like these will help give the community a better understanding so members can provide more thorough responses.
Same thing with iCloud. What is happening when you try to sign in there? Are you getting an error? We see you posted an image of the iCloud sign in page, are you having a problem with that sign in message? What is happening when you press the Continue button to proceed with signing in on the message?
In the meantime here's some articles that may help:
If you can't connect to the App Store, iTunes Store, or other Apple services
If you can't connect or sign in to iCloud
Cheers!
