I have this issue, when changing my app from x86 to x64 (or deploying as x64) after a while it crashes my xaml editor forever (even when i switch back to x86 again). How can I make my app x64/, and why I have this issue?

Welcome to Microsoft Q&A!To further troubleshoot this problem, I would appreciate your help to collect the following information.
- Did the XAML designer crash or did the application itself crash?
- Build a new UWP project, will the same problem occur when switching from x86 to x64？
Thank you，

- new uwp project doesn't work either.

2022-10-21T06:05:34.91+00:00 This problem also occurs with an empty UWP project, indicating that it has nothing to do with code writing.
Your question seems to be more related to Visual Studio, I will look for engineers of Visual Studio Team and check this. -

Then, create a new project and check again.
If it persists, please share us a screenshot about your XAML designer so that we can investigate it further. -
