Hey there Reapin Russian, This sounds like the known issue we have posted in our announcements. I'll copy paste it over in case you missed it.
With profile sign-in settings set to “Lock it down”, you may be unable to sign-in again after playing a game, then signing out. Workaround: Hard reset the console (hold down the button on the front of the console for five seconds until it fully powers down, then power it back on).
Another workaround you could try until we get a fix in place is to just switch to the Energy Saver power option in the power settings. Please let me know if you have any other questions and have a great day!
