I created a new C++ project in Unreal 5.3.2 and right off the bat, it won’t compile.
Initially it wouldn’t even create until I deleted some MySQL Plugin directly from the Engine’s plugin directory.
Now it simply won’t compile. It won’t compile from the Engine and it won’t compile from Visual Studio 2022.
When I try to compile from the engine, it returns this message in the output log:
unreal engine Warning: RebindPackages not possible
When I compile from VS 2022 17.8.5, the output returns:
Severity Code Description Project File Line Suppression State Details
Error CS8604 Possible null reference argument for parameter 'other' in 'void HashSet<string>.UnionWith(IEnumerable<string> other)'. BuildGraph.Automation H:\Unreal Engine\UE_5.3\Engine\Source\Programs\AutomationTool\BuildGraph\BgScriptReader.cs 1640 Active

I have verified my Unreal Engine files with the Epic Games Launcher.
I tried a full reinstall of Visual Studio 2022 following the instructions from the UE 5.3 documentation. Same problem.
I have a separete installation of Unreal Engine 5.0.3 and projects still compile fine there. I don’t understand why 5.3.2 doesn’t compile.
Also for some reason, there is a permission error in Windows when I try to delete the Intermediate folder from my new project’s directory.
