ANR on art::DexFile::FindClassDef(art::dex::TypeIndex)

Question

Firebase Crashlytics reported an ANR which I couldn't find out what is causing the issue. It appears that there is something wrong with ArtDexFileLoader.

Since there isn't any reference to my codes or any other 3rd party libraries that I used, I don't know how to fix the issue.
