How the engine finds the map to load?

I found this not-working solution, Post , I know why this happened to me, I just

renamed the ThirdPersonCPP to MyGameAssets and this issue started.

I renamed MyGameAssets to ThirdPersonCPP and the issue is not fixed.

I fixed redirectors and still the issue is not fixed…

waiting for an working answer, where are the unreal dev’s since this issue is very common and I found many posts about this but nobody replied with fix.
