Hi,
RHBinder__ShimExeMain, I captured this function by using a CPU profiler tool when an event of Windows.Foundation.EventHandler is trying to triggered which mean everytime an event is going to be triggered then the UWP system will call through RHBinder__ShimExeMain.
The issue which I am facing is when UWP system try to trigger the event, look like it was stuck in a loop and cause CPU usage go up to 100%, this issue is randomly occurred.
Could you please tell me what is RHBinder__ShimExeMain do? Is the issue I mentioned above is a known issue and occurred on specific Windows version?

here are capture files I mentioned above in case you need, one is captured while the issue occurred, the other is captured in normal state, you can open it by using Very Sleepy tool:

2020-07-01T05:12:32.247+00:00 You mentioned that this happens randomly, right? The log does not contain much useful information. Now my question is which event handler causes the problem and in which scenario it happens. Could you reproduce this issue when you debug your app?

2020-07-02T05:09:16.957+00:00 I reproduced this issue once 2 weeks ago and I can't reproduce until now but this issue keep coming back with some users.
Which event handler causes the problem? VungleSDK, code like below:
sdkInstance->OnAdStart += ref new Windows::Foundation::EventHandler<VungleSDK::AdEventArgs ^>(vungleDelegate, &VungleDelegate::OnAdStart)); -

2020-07-02T05:10:40.59+00:00 and in AppxManifest.xml which was extracted from my project appx package, there is something like this:
<Extension Category="windows.activatableClass.inProcessServer"> <InProcessServer> <Path>DummyName.dll</Path> <ActivatableClass ActivatableClassId="VungleSDK.AdEventArgs" ThreadingModel="both" /> </InProcessServer> </Extension>Regarding to 2 capture files, with the HighCPU one, you can see that "DummyName" module is executed and it triggered some above callstacks multiple times so I want to know what was these callstacks is doing? Do you think this issue come from VungleSDK?
Thanks,

2020-07-02T08:22:24.45+00:00 The code shows the event handler works when the SDK is created. VungleSDK is a third-party library that we do not support. To confirm whether this issue is caused by the third-party library, I suggest that you could update your app with a non-ad version to see if the issue still exists. If this issue is related to the third-party library, you might need to ask in its official forum.
