title: Why do i get this error in Unreal Engine 5 when trying to Package android apps?
body: <p>Hi guys iv been struggling since yesterday and i have run out of ideas. i build a little android game from a youtube tutorial and when i was done i realised i need android studio to package the game. so i downloaded it and ran it for the first time. i followed Unreal engine documentation to install android studio and make it work with Unreal engine 5. long story short im getting these errors and warnings after setting up everything identical to what they said i should do. i have reinstalled android studios several times. i have version 3.5.3</p>
  <p>i have java jdk 18.0.1</p>
  <p>here is the full output log in Unreal engine (filtered for Errors and Warnings). Any help would be much appreciated:</p>
