PackagingResults:Error: Error Launch failed! Unknown Error

I have a Packaging problem for android devices. A few days ago all be good, after try launch on another fone for testing (HTS), but unreal engine can’t compile and stopped after several seconds. Trying on another versions engine.
Format all files, install new windows 10 x64, Download engine, VS, Andriod apk, set new developer mode on devices, create new empty project with blueprint only, and another project with C++. Set all paths in Android SDK. But Engine don’t launch on modile. But can launch on desctop. Testing on differrent engine version, problem is remains.

From Output Log:

Hey Odmix,

Try adding a New C++ Class based on None to the project and then try to launch again. You’re getting the error:

LogPlayLevel: UnrealBuildTool: ERROR: No modules found to build. All requested binaries were already part of the installed engine data.

This usually is resolved by simply adding that empty C++ class to the project that I suggested above.

Have a great day

Hey Sean

Oh, thanks! I forgot about this action after reinstall windows and other programs) Hope this problem not reapeted if I use another mobile

Have a great day
