Canary Build 28020.1611 fails to boot WinRe, because winload.efi cannot verify signature.

Build 28020.1611 fails to boot WinRE with this error showing in the screenshot below.

The digital signature for this file couldn’t be verified.

File: \windows\system32\winload.efi

Error code: 0xc0000428

The problem was already happening on previous Canary build 28020.1546 and carried on on current build.

Canary2820-1611Problem

I compared the WinRE winload.efi on Dev that does not have this problem versus Canary that fails loading WinRE, you can see below that in Canary build the Catalog signature is completely missing and for that reason the signature cannot be verified by Dell XPS 8930 and Dell XPS 8940 firmware.

Why is the Catalog signature missing on WinRE winload.efi on Canary Builds?

Note that the winload.efi for the normal OS boot has the Catalog signature present on both builds and it has no problem booting.
