WinAppDriver + Appium return hidden elements as "no such element" for .NET framework 4.8.1

[zewer]

WinAppDriver 1.2.1 Appium 1.19.1

Hello I'm automating WPF application and recently my team did minor application upgrade from .NET framework 4.7.2 to the 4.8.1 After that WinAppDriver + Appium started returning all hidden elements as they are not present anymore.

[STDOUT] {"status":7,"value":{"error":"no such element","message":"An element could not be located on the page using the given search parameters."}} [WD Proxy] Got response with status 404: {"status":7,"value":{"error":"no such element","message":"An element could not be located on the page using the given search parameters."}}

I have tried to work with PageSource and can confirm they are not there anymore. Inspector.exe can still see all of them

Is this a known issue? Any possible solutions for this situation? P.S. For 4.7.2 .NET Framework WPF application everything was visible perfectly

If inspect.exe can find the element then winapp driver will find the element.
