unreal lightmass executable is outdated

[dredgeho]

Downloaded zip file and extracted.
Switched unreal version to Oculus fork 5.4.3
Says I need to recompile.
Recompiled in Visual Studio
Open project and wait for it to finish compiling shaders.
Then it says unreal lightmass executable is outdated rebuild in Visual Studio
Look up this error because WTF
They say find lightmass in visual studio. I find it but it's not separate where I can only build lightmass.
Rebuild the folder lightmass is under (whatever it's called ... program something) compiles no errors.
Go back into project file.
SAME THING "unreal lightmass executable is outdated"

Do any of the examples work? How about a webpage that easily describes how to do this? To this day no Unreal examples have worked for me.

Dear @dredgeho

Thank you for reporting your issue. We cannot reproduce this with the very same setup and steps you described.
It looks like you're having an issue with your local setup.

Apparently, UE can have issues with lightmass, here's a link to the UE forum which has pointers to help:
https://forums.unrealengine.com/t/unreal-lightmass-executable-is-outdated/680381/7
(Use your powershell to rebuild lightmass)

We are sorry to hear about your bad experience,
can you reproduce this with a fresh checkout?
(Checkout, Run Setup.Bat, Run GenerateProjectFiles.bat, and then use a fresh extracted copy of the downloaded zip here).
Also, please check if your path to Unreal Engine is long. We achieve best results when using a very short path (e.g. checkout directly to C:\UE ).
