Check your Windows antivirus logs SWS. Windows' Defender usually blocks Grub2Win.

Heitor, how are you, and SWS, downloading the preview release of Windows 11? And why are you doing it?

Windows' security is very tight. and frequently impacts executable downloads and installs. Check it's security logs.

Hi,

This issue is fixed in Grub2Win version 3.0.0.6 Build 1778 or higher.

It was triggered by changes in the way Windows 11 version 26200 processes certain files.

Thanks,

Dave
