Did you try to run directly the UnrealbuildTool.exe? It is located in the Binaries folder…
I changed your command:
"C:/Program Files/Epic Games/UE_5.5/Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.exe" -projectfiles -project="C:/Users/Rüveyda/Documents/Unreal Projects/MyProject/MyProject.uproject" -game -rocket -progress
Also open the Build.bat file, inside a text editor. It has some documentation in the first lines. (if you want to use the .bat file)
Hope it helps…
