java.lang.ClassCastException: android.view.ViewRootImpl cannot be cast to android.view.View

[molodoychelovek]

🐛 Describe the bug The issue arises in the ThemeManager class within the application. Specifically, there seems to be an error related to class casting in the getRelativeLeft and getRelativeTop methods.

⚠️ Current behavior When certain conditions are met, the application crashes with a ClassCastException in the ThemeManager class.

Error:

java.lang.ClassCastException: android.view.ViewRootImpl cannot be cast to android.view.View
