It seems like you encountered an issue with the assigned access kiosk account and the user profile service on your computer. To resolve this problem, you can try the following steps in the Recovery Environment:
1. Boot your computer using the USB installation media.
2. On the Windows Setup screen, select your language preferences, and click "Next."
3. Click on "Repair your computer" at the bottom left of the screen.
4. Select "Troubleshoot" and then "Advanced options."
5. Choose "Command Prompt" to open the command prompt window.
Once you have opened the command prompt, you can try the following solutions:
Solution 1: Repair user profile service:
1. Type the command: `sfc /scannow` and press Enter. This command will scan and repair system files.
2. After the scan completes, restart your computer and check if you can log in to the kiosk account.
Solution 2: Enable the hidden admin account:
1. Type the command: `net user administrator /active:yes` and press Enter. This command will enable the hidden admin account.
2. Restart your computer and log in using the newly enabled admin account.
3. Once logged in, you can make the necessary changes to fix the assigned access kiosk account or remove it if needed.
If the above solutions do not work, you can consider restoring your system to a previous restore point if one is available. This can be done from the Recovery Environment as well.
Please note that if none of these solutions work, you may have to consider resetting your PC as a last resort. Resetting the PC will remove all installed programs and files while keeping your personal files intact.
