Hi OlafKJ,
I'm Christine, a Windows user like you. I can see here that your Settings app freezes when you're trying to open the Lockscreen or background. No worries,I'll do my best to help you.
May I know when did the issue start? Is there any changes made?
Please check and follow the steps below:
- Repair Settings
Please click Start Menu and type Powershell, right click on it and choose Powershell(admin), copy and paste the command below and hit enter.
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Once the process is finished, restart the PC and check if the issue still persists.
- Please try to run the sfc scannow to check if there's a corrupted system file. Kindly follow the steps from the link below:
Please click start menu and type cmd, right click on it and choose CMD with Admin.
Type sfc /scannow and hit enter. NOTE: There's a space between c and /
