Error 0xC1900101 - 0x40021

Hello,

I'm trying to upgrade my Windows 10 to Windows 11 but I've got a blue screen with this error :
INVALID_DATA_ACCESS_TRAP

After that, when I came in Windows 10, the configuration of Windows 11 tell this error :

0xC1900101 - 0x40021 : The installation failed in the SECOND_BOOT phase with an error in the BOOT operator.

(This error occurs when I'm use the ISO file)
(I've already tried Windows 11 Installation Assistant)

Thanks

Also, I've an Ubuntu dualboot on my laptop

Thanks for all that info. *Thumbs Using it, I tried to find a solution to the 0xC1900101 - 0x40021 error but was unsuccessful. I'm going to take your advice and wait for Microsoft to get its act together before attempting another 2004 upgrade.
