Running this app is not important for me,

But just shared this log, so that you may aware of it.
May be, this crash is happening bcz of some unknown bugs inside microG.

Start with the supplied crash log, especially ContextImpl.getSharedPreferences and the com.google.android.gms.ads stack entries. Determine whether the failure is in GmsCore or the app's bundled, obfuscated code. Done means identifying an actionable GmsCore change or documenting that the report is outside this project's code.
