To Reproduce
Steps to reproduce the behavior:

1. Play a video on YouTube
2. YouTube expects a PoToken
3. GmsCore replies performs a request to get the DroidGuard program when it should cache it instead

Expected behavior

GmsCore should cache the program.

Screenshots

Note that I am running a specific environment where I have modified YouTube for debugging purposes. The issue may originate from that, but it is highly likely not the cause of the problem:

System
Android Version: 13

Start with FallbackCreator.kt, HandleProxy.kt, HandleProxyFactory.kt, and DroidGuardHandleImpl.kt from the reported stack traces, then reproduce the YouTube playback flow. Trace why the DroidGuard program is fetched again and why the native library is opened through another class loader. Done means the program is cached without repeated /androidantiabuse requests or the unimplemented-operation error.
