Packager stuck at "Launching UAT" and "Setting up ProjectParams" on UE 4.25.0

It seems like the issue was caused by the deploy settings which were set to “Copy to Device”. Setting it to “Do Not Deploy” allowed the packaging process to move to the next step.

does anyone know why is the packager stuck building at the “Launching UAT” phase which is stuck “setting up ProjectParams”?

I’m trying to build a Linux server.

As you can see in the screenshot, it’s been stuck more than 4 hours.

I’m on a desktop PC with an i7 9th gen. I’m building the server with the UE 4.25.0 I compiled from source.

I have tried:

  • Updating my linux toolchain v16_clang-9.0.1-centos7
  • Restarting Unreal
  • Restarting Windows
  • Launching Unreal by running UE4Editor.exe as admin
  • Launching Unreal through the project’s sln file in Visual Studio

Where did you exactly found the “Deploy”? I mean I have this error when launching my game in my android device but there is no option there to change the Deploy. Only if I make a new profile.

Its at the bottom of the Window > Project Launcher > profile settings for me

. I’m building for Windows and Linux
