Stockfish not loading in Chrome

Hi.

I'm running Version 90.0.4430.93 (Official Build) (x86_64) of the Google Chrome browser (on a 2016 MacBook running Big Sur).

In the past few days, the in-browser Stockfish engine has stopped loading in Chrome. The switch to turn it on doesn't appear at the top of the game score in any Analysis Board views on Lichess.

I don't see any errors in browser's console.

There's no problem in Safari or Firefox (but Chrome is the browser I use).

Any help would be appreciated.

Thanks,
Tim

As usual, clear browser history (you will loose your logins on other sites, so be careful) or change browser (BTW I like Firefox better than Chrome).
