Error in building on 5.4 on android, PackagingResults: Error: Unknown Error

Hey! It’s not the case. I disabled and enabled plugin, tried new projects and clean… And it seems like the problem is in c++.If i make a c++ project, it just throws me an “Unhandled exception: System.IndexOutOfRangeException: Index was outside the bounds of the array” but I guess it has to do something with visual studio (not sure)

I used blueprints and followed the instruction from this post: WARNING:R8: An API level of 34 is not supported by this compiler. Please use an API level of 33 or earlier (App must target Android 14 (API level 34) or higher) - #15 by Skyboy
And it works only for blueprint projects, tho it still throws:
" UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 34
UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): This Android Gradle plugin (7.4.2) was tested up to compileSdk = 33
UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): This warning can be suppressed by adding
UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): android.suppressUnsupportedCompileSdk=34
UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): to this project’s gradle.properties"
I guess the problem is in gradle.properties, but I have no idea where to find it xD
