Avalonia app crashes on exit (.net framework only)

Describe the bug
.net framework Avalonia app crashes on exit. The crash is not visible unless debugging but it is present also in Event Viewer -> Application logs.
This does not repro for .net core apps.

Desktop (please complete the following information):

• OS: Windows 10 21H1
• Version 0.10.12
