MAUI application error due to entry element in background operation

[TurlovDV]

Description

I am developing an application where there is support for background work, but an error has occurred that I cannot fix. The essence of the error in the application is that if you exit the application, leaving it in the background, and then log in again, the error System.ObjectDisposedException: 'Cannot access a disposed object. Object name: 'Microsoft.Maui.Platform.Maui AppCompatEditText'.'

I found a pattern that the error directly depends on the presence of entry or editor elements on the xaml display page, with them wrapped in a frame (without working fine).

Steps to Reproduce

1. Create a MAUI app
2. Enable background service
3. Add entry or editor wrapped in frame
4. Exit the application in the background
5. When you re-enter, an error pops up
