Can't open anything in 5.3.1

Development Getting Started & Setup
1

It’s been a while so long in fact I don’t even recognize the forums anymore. I installed 5.3.1 and tried to open a new project and I get an error. I am basically just stuck right out of the gate returning to this.

Here is what it is telling me:

Assertion failed: IsValid(Platform) [File:D:\build++UE5\Sync\Engine\Source\Runtime\RHI\Public\DataDrivenShaderPlatformInfo.h] [Line: 189]

UnrealEditor_RHI
UnrealEditor_RHI
UnrealEditor_RHI
UnrealEditor_WindowsDeviceProfileSelector
UnrealEditor_Engine
UnrealEditor_Engine
UnrealEditor
UnrealEditor
UnrealEditor
UnrealEditor
UnrealEditor
UnrealEditor
kernel32

I’m lost I am basically starting all over again with the engine so I have no idea what this one even means.

EDIT: I got it there was a section in the defaultengine.ini causing this issue. I removed this section and everything works again.

See you already fixed this, but RHI is your selected renderer (directX, Vulkan), was it an unsupported mode?

Yeah so in the project I was attempting to open I had 6 lines in the defaultengine.ini that were related to this stuff I commented those out of the file and it was fine after that.
