Every time I want to pack an android project (android multi) I get this error:

```
UATHelper: Packaging (Android (ASTC)): ERROR: Cook failed.
UATHelper: Packaging (Android (ASTC)): (see C:\Users\Lennard\AppData\Roaming\Unreal Engine\AutomationTool\Logs\E+Program+Files+Epic+Games+UE_4.20\Log.txt for full exception trace)
PackagingResults: Error: Cook failed.
UATHelper: Packaging (Android (ASTC)): AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)
UATHelper: Packaging (Android (ASTC)): BUILD FAILED
PackagingResults: Error: Unknown Cook Failure

```

I found out that this error is related to the ASTC Texture Format (all others works fine).

I tried to pack a blank scene and I have this Problem since 4.18. Windows was completely reinstalled several times in the meantime.

Normally I install the UE4 first, then I install Codeworks from the UE4 files while the launcher and the editor are closed!
