playwright错误：UnhandledPromiseRejectionWarning：TimeoutError：等待firstPage代理失败：超时超过30000ms

Question

const playwright = require("playwright");

(async () => {
  for (const browserType of ["chromium", "firefox", "webkit"]) {
    const browser = await playwright[browserType].launch();
    const context = await browser.newContext();
    const page = await context.newPage('https://google.com/');
     await page.screenshot({ path: `example-${browserType}.png` });

  }
})();

我已经尝试运行此代码段。如预期的那样，需要截取铬和Firefox的屏幕截图。但是尝试从Webkit截屏时会引发超时错误。但是，local-webkit随playwright一起安装。

我也是。在我的本地MacBook和Github Actions Mac上都会发生这种情况
