    Windows 11 Installation Error Code: 0xC1900101 0x40021


    I tried installing Windows 11 using ISO but I get a BSOD at the end INVALID_DATA_ACCESS_TRAP with the error:Error Code: 0xC1900101 0x40021The installation failed in the SECOND_BOOT phase with an error during SYSPREP_RESPECIALIZE operation.The windows 11 update prompt now disappeared from Settings->Windows Update, while Windows Installation Assistant and PC Health Checks still state that the PC is fully compatible. How can I solve this?

    :)
