Multiple inputs in quick succession cause an FatalExecutionEngineError exception with Korean IME

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

---

[severity:It's more difficult to complete my work]
When I quickly enter Korean characters in WPF Program(DataGrid, etc...), the program suddenly quits
This phenomenon mainly occurs in Windows 11. The test environment is Windows 11, 23H2.

IDE : Visual Studio 2022
Framework : .Net Framework 4.81
Platform : WPF

To aid understanding, source code, video, and call stack are attached.

I encountered a similar issue when inputting Japanese. still no solution to resolve.

I have the same problem.
The exception FatalExecutionEngineError always occurs when typing in Korean very quickly and pressing Enter in succession in the GridView.

The last reason the exception occurs...

private void VerifyTextStoreConsistency()
{
if (_netCharCount != TextContainer.IMECharCount)
{
Invariant.Assert(condition: false, "TextContainer/TextStore have inconsistent char counts!");
}
}
