Android launch stuck at 'requesting "WorldGridMaterial" from cooker'

Hi Everyone!

I am trying to Launch my game on my Android device. It Builds successfully, but when the engine tries to Launch on my Android device it stucks. The Project launchers Output logs last line is: Starting: Intent { cmp=com.YourCompany.AndroidProject/com.epicgames.ue4.SplashActivity } That means all I see on my phone is the splash Screen. The cmd that starts when launching stops at: LogCook: Display: Requesting file from cooker …/…/…/Engine/Content/EngineMaterials/WorldGridMaterial.uasset. After this, nothing happens, no matter how Long I wait. The Launch stucks here and stays here, without an error. I really want to get started with Mobile game development. Any help is appreciated!

I have the very same issue. Any help?
What phone do you use? I use an Asus Zenfone 3

I use Samsung Galaxy J5 2016. The issue still presists on my side. Any information about your PC hardware?
