I’ll be providing a relatively easy fix that ended up working after 1 week of R&D! so new source code devs like me won’t have to research much on this topic.
As far as I know Turnkey errors are related to redists, SDKs and pretty much integration issues…
if you have wrong version of VS or required redists, you are likely to stumble across this error because the “AutomationTool” won’t compile inside the source code…
so to fix AutomationTool compiling errors (which I am pretty sure will have warnings and errors like OH NO YOUR MAGISK.NET HAS SO MANY VULNERABILITIES!!! so to fix this error you have to increase the version of your MAGISK.NET 
by going into automationtool.csproj, automationutils.automation.csproj (hope this name is right) and in gaunlet.csproj (I am writing with my weak memory, these names might be wrong lol)
GITHUB REFERENCE (YOU CAN ONLY VIEW THIS IF YOU ARE INSIDE EPIC GAMES ORGANIZATION! https://github.com/EpicGames/UnrealEngine/commit/360060ea33d92fe562e256456bb51197788119f0)
so just increase the MAGISK.NET-Q16-HDRI versions by 1 till yours is working (I increased mine from 14.7.0 to 14.9.0)
anyways if this doesnt work… (I believe this will fix half the issues) even after this you are having issues then you have to
heres the code you need to modify inside source code…
(THANKS @muggyshoT for this) note these files are inside
Engine/Source/Programs/AutomationTool/Scripts/CheckForHacks.cs line 87
Logger.LogInformation("Scanning files... [{Arg0}]", FilesToCheck.Count);
and
Engine/Source/Programs/AutomationTool/BuildGraph/BgScriptReader.cs line around 1900 (you have to find it yourself)
if (users != null)
{
report.NotifyUsers.UnionWith(users);
}
after this I am pretty sure all your automation tool related issues and turnkey related issues will be fixed…
otherwise bro just check your redist versions and see are they compatible with your engine version LOL!
anyways have a good day, let me know if you still have issues… we can surely fix it together
