Hi Jaymik, This class (MemoryMonitorOptions) was indeed introduced in Beam 2.50.0.
My guess is that somehow dependencies were upgraded only partially (for example, just the Runner module, but not Core). A good way to make sure that all dependencies are upgraded correctly is to use a BOM (Bill of Materials) and omit pinning a specific <version> for every Beam artifact. Please take a look at https://beam.apache.org/blog/managing-beam-dependencies-in-java/ and see if it helps. In case it still doesn't work, running "mvn dependency:tree" might help understanding which dependencies are being pulled.
