Why my Visual Studio 2022 Crashes when added new Windows Form UI in CLR Project?

Question

Following This Tutorial Video, I'm keep Experiencing fatal crash at Adding new WinForm UI item. (at 3:10~ in video) followed Exactly the video's tutorial.(the video gets an Error too, but It's not fatal as I crash.)

I Made new CLI Empty Project(.NET Framework) in Visual Studio 2022. Then in Project Properties, I changed Platform to Win32, Configuration Properties -> Linker -> System -> SubSystem to WINDOWS, Linker -> Advanced -> Entry Point to main, and Added new Item -> UI -> Windows Form.

the only difference i noticed are hardware and Visual Studio 2022. it crashes after being pale

New WinForm.h Should generate Without Crash in my Source Files folder as well in the Video Tutorial

Hi @Gyumin Kang , 

Welcome to Microsoft Q&A! 

I couldn’t reproduce your issue in Visual Studio Professional 2022 version 17.11.5. But I found the similar issue:

Adding resource for C++ application crashes Visual Studio - Developer Community 

It may be a Windows issue. You can refer to Quin Tosch’s suggestion to manually create the following key and value:

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main

Name: JScriptReplacement

Type: REG_DWORD

Value: 0 

Then, reboot the computer and add the Windows Forms UI again. 

Sincerely,

Anna
