My webassembly app closes as it opens

[sheqo]

Hello, I have created an interface and I want to show it on the web with Webassembly. According to the QT documentation, I installed emsdk and successfully converted my project to webassembly format. When I run my project through QT Creator, it appears instantly on the website, but when interacting with a button in any way or even if I move the cursor over a button, the screen goes blank. can you help me i hope i explained the situation well

@sheqo EDIT: I tried it on a new project and web assembly works fine, but there is something wrong with this project, can you think of anything?
