i am facing a weird problem . i am using compose richtext printing .https://github.com/halilozercan/compose-richtext and in my debug build its okey but after releasing to play store its not working . i tried release build with debuggable true still no problem . so am releasing close testing android 5 times a day . and still same problem . i reverse back to my old compose version , no luck . tried current alpha , no luck .
1 . am i doing it right to release closed test for no reason ? is there a proper way to debug release build that reproduce exact apk like google play ?
2 .how can i remove closed test apk from play store ? my version code keep increasing .
3 .whats the problem with my release build ?
here is the release error when i see logcat .

If you build an release version with proguard enabled, a mapping file is produced called mapping.txt in your build folder. This file can be used to deobfuscate the error stack trace using Proguard Retrace. https://www.guardsquare.com/manual/tools/retrace

Then you can actually see where in the “original” code, the null pointer happens.

fixed :
need to minify false ( pro-guard -keep ) the library and its dependencies .
