We've just released a patch for RAD Studio 10.3.3 which resolves the following issue:

An issue that prevented an Android service running because it could not load its native library. This only affected applications packaged as Android App Bundles. The base APK generated from an AAB has the extractNativeLibs manifest attribute set to false. In this case, the Package Manager does not extract the library to the filesystem when installing the application, causing the Android service to pass the dynamic linker an incorrect absolute path to the native library.
