Similar issues which turned out to be related to various dependency/build problems:

https://github.com/google/ExoPlayer/issues/10060

https://github.com/google/ExoPlayer/issues/9704

Based on https://github.com/google/ExoPlayer/issues/9704#issuecomment-975390727 I would suggest checking that you're depending only on the Android Guava variant (and not the general JRE one).

I don't believe this is a bug in ExoPlayer - but more a problem related to your build environment.
