How to disable images to download?

I tried to use the code, but it didn’t work.

                   // disable images to download
                    await page.SetRequestInterceptionAsync(true);
                    page.Request += (sender, e) =>
                    {
                        if (e.Request.ResourceType == ResourceType.Image)
                            e.Request.AbortAsync();
                        else
                            e.Request.ContinueAsync();
                    };

error like this:

Protocol error(Page.navigate): Target closed. (NetworkManager failed to process Fetch.requestPaused. Value cannot be null.
Parameter name: key.    at System.Collections.Concurrent.ConcurrentDictionary`2.ThrowKeyNullException()
   at System.Collections.Concurrent.ConcurrentDictionary`2.set_Item(TKey key, TValue value)
   at PuppeteerSharp.NetworkManager.OnRequestPausedAsync(FetchRequestPausedResponse e)
   at PuppeteerSharp.NetworkManager.Client_MessageReceived(Object sender, MessageEventArgs e))

environment:

Thank you for your answer. Maybe I misunderstood the versions of chrome and chromium. 😦
