Windows Terminal crashes when copying text to clipboard

### Windows Terminal version

1.22.12111.0

### Windows build number

10.0.26100.4946

### Other Software

_No response_

### Steps to reproduce

Mark multiple lines of text in cmd window with the mouse.
Then press Enter.
Instead of copying to clipboard and removing the white background (indicating the marked text), Windows Terminal closes all of its windows. In the Event Viewer I see the following error report:

### Expected Behavior

I expect that the text be copied to clipboard and the Windows Terminal keeps running.

### Actual Behavior

Windows Terminal crashed and closed all of its windows.

Start by reproducing the crash in a cmd window with Windows Terminal 1.22.12111.0 on Windows build 10.0.26100.4946: mark multiple lines and press Enter. No source file or test is named; use the reported Windows.UI.Xaml.dll crash details to locate the affected clipboard path, then verify that copying leaves the terminal running and add or update coverage if the repository provides it.
