Add your package as an exception in your ProGuard.

-keep class com.mappls.sdk.maps.** { *; }

    Thanks buddy working can you please explain why this error thrown because I know that in release build the code is obfuscated that's why we using this ProGuard rule but app working correctly in release build when directly installed from android studio even I build has .aab and installed its working correctly but if I install it from play store only the app crashes . – Mohanasundar Oct 21 '22 at 04:26
  • It's okay not to obfuscate SDK codes since it is useless to reverse engineer them. – Lawrence Gimenez Oct 21 '22 at 07:55
