Description

Description
One of our customers can't work after runtime updated to 99.0.1150.39 (evergreen). The content is not loading any more. The area of the webview is grey. Our product hasn't changed. Replacing the runtime by 94.0.992.31 fixes the problem. The 94.* is the last one working version. All newer versions fail too.
We load the content by setting the Source property to a local html file (url = file://...). The application is accessed via RDP.

Version
SDK: 1.0.1054.31
Runtime: Evergreen 99.0.1150.39
Framework: WinForms (x86)
OS: Windows Server 2016 Standard

Repro Steps
To prove that it hasn't to do with our productive code, we implemented a mini sample capable of loading certain targets or a local file. Interestingly, on our test systems and many other customers it works with both runtimes, but at one customer it works only with 94.0.992.31 and fails with 99.0.1150.39. To prove the difference we replaced the contents of the evergreen installation (99.0.1150.39) with the contents of the fixed version (94.0.992.31).
Compile solution, start it, click on "Test load..." and then on "Load".
