How to fix it

Upgrade the TPM to version 2.0. If it persists, make sure the device is not in two groups with different Autopilot profiles assigned.

Find it on the device

Collect the Autopilot diagnostics on the device (press Shift + F10 during OOBE for a command prompt), then look for the code:

powershell3 lines
mdmdiagnosticstool.exe -area "Autopilot;TPM" -cab C:\Temp\autopilot.cab
Get-WinEvent -LogName "Microsoft-Windows-ModernDeployment-Diagnostics-Provider/Autopilot" -MaxEvents 200 |
