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
