The code execution cannot proceed because edgegdi.dll was not found


This issue happens for Windows 10, version 2004 (20H1) build:19041 related with a regression on gdi32.dll. There are lots of incorrect fix suggestions in internet for this issue that instructing rename and copy “edgemanager.dll” under system32 folder as “edgegdi.dll” and this is a BIG mistake.

Yes, this workaround immediately mitigate the problem but when you do a windows update your system most probably crash and you need to recover it. Because the sanity check of this DLL is not correct that is not suppose to be there that would crash your system while csrss.exe loading this DLL and you will face a BugCheck with 0xc000007b

This issue will be fixed with August 2021 3rd week updates, 2021-08 C , KB5005101 (not released yet while i am filling this post)
for Windows 10 2004 / 20h2 / 21h1
