Snapdradon Profiler (v2020.3.0.9242020) hangs when capturing a snapshot from a Vulkan application.

Application: Draw Cube from https://github.com/LunarG/VulkanSamples/tree/v1.2.141
Device: S20
Model: SM-G981U
Development OS: Windows 10

Steps:
* Added the following permissions to the app's manifest:
    <uses-permission android:name="android.permission.INTERNET"
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
* Connect to a Device
* Launch Application
* Select Application
* Take Snapshot
* Profiler gets stuck on "Retrieving Snapshot". The message "Working On: Preparing snapshot. Device may freeze temporarily." always showing. Application stills shows on phone.

I made sure not launch Android Studio in the same session.

I got a snapshot for Hello Triangle https://github.com/KhronosGroup/Vulkan-Samples , but am unclear on what is different about these two apps that made the profiler work.

I suspect this is related to the fact that the draw cube only renders once. Is there a way in Snapdragon Profiler to queue up the capture of a snapshot like Renderdoc allows?
