Export error for android HELP

I’m trying to export a game for my android mobile phone but I keep getting errors like this:

UATHelper: Packaging (Android (ATC)): ERROR: T:/NVPACK/android-sdk-windows/tools/android.bat failed with args --silent update lib-project --path JavaLibs/downloader_library --target android-29
UATHelper: Packaging (Android (ATC)): (see C:\Users\Tomic\AppData\Roaming\Unreal Engine\AutomationTool\Logs\T+Program+Files+(x86)+Epic+Games+Eu+UE_4.19\UAT_Log.txt for full exception trace)
UATHelper: Packaging (Android (ATC)): AutomationTool exiting with ExitCode=1 (Error_Unknown)
UATHelper: Packaging (Android (ATC)): BUILD FAILED
PackagingResults: Error: Unknown Error

If I set export to SDK 24 and NDK 19 or SDK 29 and get the same error. If I went back to the path settings (SDK, NDK, ANT and JAVA) I would get something like this: http://prntscr.com/pp6fkz
They would all be set in the JAVA folder.

And before export paths were fine.

Can you help me solve this problem? I’m currently using Unreal Engine 4.19.2

All the best,
