I’m making a game for Quest 3 in UE 5.2.1. I’ve been able to make development builds fine, but now I want to test the game without print strings or debug lines, so I set the Build Configuration to “Shipping” and checked “For Distribution” as true in the project settings. I also created a .keystore and set that up in Platforms/Android/Distribution Signing with the correct password and everything.
When I package it via Platforms>Android>Package Project with “Android (ASTC)” and “Shipping” selected, It builds fine until it reaches “> Task :app:packageRelease”, then it gives me this:
> Task :app:packageRelease FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:packageRelease'.

Seems like the main issue is that a file in the temp folder isn’t being allowed for deletion. I don’t know what could be causing this.
When I untick “For Distribution” it compiles fine, but obviously I want to be able to make a distribution build.
I’ve verified that my keystore password is set correctly. I’ve tried reinstalling android studio several times and even tried using a separate installation for jdk instead of Android Studio’s built-in one. I’ve tried different sdk api levels. Nothing is working. I have bitdefender but that isn’t blocking any of the temp files from being deleted, at least to my knowledge. Moving the build destination folder to the C Drive doesn’t work either.
I’ve been trying to resolve this all day and am currently questioning my career choices does anyone have any idea what I could be doing wrong please help
