[bug] The debug build does not work (`npm run dev`), files are loaded, but the screen does not render (vite)

gynt commented 1 month ago

Describe the bug

When I run npm run dev, all files are loaded, e.g. CSS, .tsx files, so I get my background color. However, no html elements are rendered at all: main.tsx isn't run?. This same identical setup used to work 3 days ago. I received a Webview2 update from Windows yesterday and then it stopped working I think. There are no errors in the web console. Interestingly, release builds work just fine. The repo is here: https://github.com/UnofficialCrusaderPatch/UCP3-GUI

<html lang="en">
   <head><!--  I removed all and styles scripts --></head>
  <body class="col-12 bg-dark text-light">
    <div id="root"></div>
    <script type="module" src="/src/main.tsx"></script>
  </body>
</html>

Reproduction

UPDATE: Use a global scope await import() in your code (for importing development functionality).

I solved it. This line of code was causing the issue:

if (import.meta.env.DEV) {
  await import('../function/dev');
}

The code would set some functions in the globalThis.dev variable. The only issue remaining is, when did this stop working? We think it is because of a new Webview2 release by Microsoft, but we can't tell.

Turns out, it is the await in this code that is causing issues. Still not sure why that is suddenly an issue.
