    Heya! Looking into that right now, are the players also built with latest 2019.4?

    Edit:
    Tested on latest 19.4 and everything works as expected. Are you trying to snapshot older version builds?

    Having the same issue here. Attempting to take a memory snapshot of a remote Linux player from a Windows machine, both 2019.4.8f1. Managed Objects capture fine but Native ones fail in the logs with

    MemoryCapture: Header Serialization : 163 ms
    MemoryCapture: Metadata Serialization : 0 ms
    MemoryCapture: Capture flags Serialization : 0 ms
    MemoryCapture: Managed Heaps : 4354 ms
    MemoryCapture: Managed Stacks : 0 ms
    MemoryCapture: Managed Metadata : 126 ms
    MemoryCapture: GC Handles : 61 ms
    MemoryCapture: Native Types : 0 ms
    MemoryCapture: Native Objects : 2084 ms
    MemoryCapture: Runtime Information Serialization : 0 ms
    MemoryCapture: Native Allocation Header : 0 ms
    MemoryCapture: Native Allocation Labels : 0 ms
    MemoryCapture: Native Root References : 0 ms
    Encountered Invalid Memory Region signal
    (Filename: C:\buildslave\unity\build\Modules/Profiler/Runtime/MemorySnapshotProcess.cpp Line: 1301)

    MemoryCapture: Failed processing of Native Memory Region
    MemoryCapture: Failed processing of Native Allocation Footer
    MemoryCapture took: 6788 ms

    Additionally, the Memory Profiler UI gets stuck showing a progress bar that never goes away, giving the illusion it's still doing something.

    2019.4.8 got hit by a regression. Iirc the fix for that one landed on 2019.4.10, but in case that it wasn't that, the higher the patch release version the more likely it's fixed.
