Yeah, there is still an issue with 2.3.2 runtimes and NDK 22 - please continue using NDK 21 for now, and we will fix properly for 2.3.3. We have obviously missed updating that one line in the Required SDKs FAQ, so I will go fix that right now - thanks!
Our setup information for Android does say to always use the OpenJDK install which comes with Android Studio - if you were previously using the Oracle JDK, then this hasn't been the correct one to use for quite a while (ever since Oracle made that a commercial licence).
