[Critical] Command + V and more crashes the application (macOS 13)

Description

When developing my own application, I noticed a very serious bug: when I tried to copy and paste certain text, the application stalled and then crashed. I can note that when testing on Windows (version 11) everything worked fine.

Steps to Reproduce

1. Create a File > New .NET MAUI App
2. Add a Entry like so: <Entry Text="this is a bug" />
3. Click the added entry, press in keyboard Command + V, Command + C, Keyboard arrows left or right (macOS system) and observe the bug 🐞

Expected result: The text insertion will be successful. Actual result: the application is slowing down/crashing.

There were no errors when trying to run this bug on Windows.

[MSicc]

Has that been fixed?

@1thenikita just tested with both .NET6 MAUI and .NET7 MAUI. .NET6 still crashes, .NET7 works.

With .NET6 being LTS, this should be fixed in there as well.

I ran a dotnet workload update just before testing.
