Event ID 455

Hi NancyK1104,

Thank you for writing to Microsoft Community Forums.

We understand your concern as you are getting an event ID 455 with Error -1023 (0xfffffc01). We would like to know the Windows 10 version and Build installed? (Type
winver in Windows search/Run command) Also if you can let us know what are the troubleshooting steps performed on the PC.

Meanwhile, we would like you to perform these methods and check.

Method 1:

1. Press Windows + R key and launch
   Run command.
   
2. Copy and paste this path: C:\Windows\system32\config\systemprofile\AppData\Local\
   
3. Click on Ok and then create a folder and name it
   TileDataLayer.
   
4. Open it then create another folder and name it
   Database.
   
5. Restart the PC and check.

Method 2:

1. Click on Start Menu and type CMD, right click on
   CMD icon and select Run as administrator.
   
2. In the Command Prompt window type the following command and press
   Enter after each command
   

• cd config\systemprofile\AppData\Local
  
• mkdir TileDataLayer
  
• cd TileDataLayer
  
• mkdir Database
  

3. Restart the PC and check

Method 3:

We would also suggest you to create a local user account with Administrator privilege on the PC and check if you are able to access the TileDataLayer folder. Refer this article to
Create a local user or administrator account in
Windows 10.

Let us know how it goes.
