Binaries folder missing when launching project on android

I cloned my Project A ver 4.25 to ver 4.26. Everytime i launch my 4.26 project on android Google pixel 4 i get the following error :

ERROR: Stage Failed. Missing receipt ‘C:\Users\Nav\Documents\Unreal Projects\TestingProject 4.26\Binaries\Android\’. Check that this target has been built.

PackagingResults: Error: Launch failed! Missing UE4Game binary.

You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:

So i checked the project folder and the Binaries folder is missing, i have no idea why its not being made.

To isolate the issue i conducted the following tests :

  1. Opened a blank Third person mobile project on 4.26. This deploys fine in mobile and binaries folder is present.

  2. Cloned my Project B ver 4.25 to ver 4.26. This also deploys fine on mobile and binaries folder is present.

Seems like only my Project A cannot create binaries folder when cloned to 4.26

Desperate for help because my app crashes for some reason in 4.25 and hoping 4.26 might have a fix.
