Can You Help Me?

Not sure why you’re getting an ICE but the second screenshot seems like you might not have installed a dependency or at least it needs repairing.

Could you check if the Windows SDK and .NET SDK are installed? You can do that from the Visual Studio Installer which you can find in your Start Menu

I Am Giving You Screenshot Of What I’ve Installed Or What I Haven’t.

And Also Building The Engine Is Taking Approx 11 Hours Which Is Insane.
So I Decided To Remove Some Unused Plugins From The Folder E:\Epic Games\UnrealEngine-4.26.1-release\Engine\Plugins
But Getting Error, So There Must Be A Way To Remove Those Plugins Without Error. Now Please Don’t Tell Me To Buy A SSD.

Most likely a compiler bug. If it happens again you should report it here

Have you tried repairing?

Well… You’re not going to like my answer then :sweat_smile:.

Last time I built from source on my HDD it took about as long as it did for you. Doing so on an SSD it took about an hour.
