Puppeteer Sharp strange behaviour

You can close the page using CloseAsync:

var page = browser.NewPageAsync();
////
await page.CloseAsync();

An using block will also close the page:

using (var page = await new browser.PageAsync())
{
///
}

Puppeteer-Sharp v2.0.3+ also supports await using blocks

await using (var page = await new browser.PageAsync())
{
 ///
}
