Cannot be injected while using an external program

[ghost]

Hi.

I have a code in C# which launches via Process.Start() the executable file 3DMigotoLoader, the console appears as normal but when I launch StarRail.exe (I omit the launcher | The launcher on the video was created by me) also via Process.Start() the console displays "Found" and then closes and the code/3DMigotoLoader is not injected.
This only happens when I run with Process.Start() when I open with the mouse (like any human does) its work just normal.

I tried adding a wait time to my C# code before running the game: Didn't work

The .bat (batch) file doesn't work either.

I am not sure if this is my fault please help
