Have issue with performance of the web app

Hello,
Recently I noticed that when I open the web version of chess, my computer loads heavily. The developer console shows thousands of errors.
Here are some of them (but they are all repeated many times):
Failed to load resource: net::ERR_FAILEDUnderstand this errorAI
Failed to load resource: net::ERR_SOCKET_NOT_CONNECTEDUnderstand this errorAI
Failed to load resource: the server responded with a status of 503 ()Understand this errorAI

I don't use any extra browser extensions. Even adblock is disabled for chess.com. I tried to visit the site in incognito mode when all extensions are disabled - the result is the same and even in other browsers (I tried chrome and mozilla).

This all makes the game very difficult, because often the tab with the site does not respond. And I have a pretty good computer.

Are you accessing the site through a VPN or web proxy?

Nope

It’s not related to a VPN or traffic routing. Open the DevTools console and take a look at this disaster. Ads are spamming requests, at the very least.

Here's a sample from the console:
Uncaught SecurityError: Failed to read a named property 'alreadyInjected' from 'Window': Blocked a frame with origin "https://ef200cbfc73c6a5042392e60324c32af.safeframe.googlesyndication.com" from accessing a cross-origin frame.

CORS blocking request, why it still at this web-site at all?
