Android game crashing on Android 9 (API 28)

I have a game released on android and IOS. It was running fine on both until someone I knew with the game updated to Android 9.0. I hopped on and got the correct API 28 for codeworks and repackaged the project to include that API and sent out a beta update. For Android 9 preview test on google play it launched and passed all the test but on actual Android 9 projects it crashes. The error I am getting on google play console is:

java.lang.NoClassDefFoundError:
at com.android.a.a.g.a (HurlStack.java:109)
at com.android.a.a.a.a (BasicNetwork.java:97)
at com.android.a.h.run (NetworkDispatcher.java:112)
Caused by: java.lang.ClassNotFoundException:
at dalvik.system.BaseDexClassLoader.findClass (BaseDexClassLoader.java:134)
at java.lang.ClassLoader.loadClass (ClassLoader.java:379)
at java.lang.ClassLoader.loadClass (ClassLoader.java:312)

Because of this report I tried to package a dedicated update for just android 9 users which resulted in the same failure.

Anyone have any idea what this means and how to resolve it?

I have the same problem…
