build\bin\simulator.exe
There is no special operation, copy and paste all the components of the problem page to a new page and then run the new page is normal, very strange, when the problem backed up the project, if it is convenient, you can leave your e-mail address to send a copy of the problem project. It is not convenient to upload files here. It's just that this error is reported after switching to a certain page.
Are there any special operations? Does it reproduce consistently every time? I just tried it on my end and it didn't reproduce your problem. Can you describe it more specifically?
