We are experiencing a crashes in our WPF application. It occured only when the PC is accessed through RDP.
I am able to reproduce the issue with simple WPF app with TextBlock and StoryBoard only. This application crashes while I'm doing some action in other application.
According to general recommendations in https://learn.microsoft.com/en-us/troubleshoot/dotnet/framework/wpf-render-thread-failures I prepared the minimal solution, full dump and TTD of this issue but where should I upload this things (together it takes around 5 GB of disk space).

My scenarion where the crash occures:

  1. Connect to the machine through RDP
  2. Start my simple WPF App
  3. Start other app and interact with it.
  4. In between my simple WPF App crashes with UCEER_RENDERTHREADFAILED (while in background)

I was able to reproduce the issue also on other machines that mine.
I tried to disable HW-Rendering but it doesn't help.`enter code here

My machine on which I am experience the issuse is:

CPU: Core i7-9700K
RAM: 32GB
Windows 10 Pro
VS 2017

This is what WinDbg Preview say at the point of failure (with sxe out command):

MIL FAILURE: Unexpected HRESULT 0xd0000701 in caller: The render thread failed unexpectedly.
