3) Start Player
4) Open and connect Profiler to Player
5) Switch to "Memory" tab in Profiler
6) Open MainMenu > BugReport > Open TestCode Window

Fixed in: 2021.2.0a12
When crawling mono for it's allocated memory we report more than just the managed heaps in which the objects reside (which the CPU profiler does). We report memory allocated by mono in order to store things such as MonoClass data, these chunks are not differentiated from the normal heaps prior to Unity Versions 2021.2.0a12, 2021.1.9, 2020.3.12f1, 2019.4.29f1 or newer. Previously this was intended behavior, but starting from these versions, managed heap sections have the highest bit set if they aren't used for heap objects, i.e. `(snapshot.managedHeapSections.startAddress & 1ul << 63) == 0` signifies managed object heap sections.
