What I usually do is to click slowly in the reCAPTCHA area and hold down the left mouse button for a second or longer before releasing the mouse button, that always works for me.

You can possibly try a User-Agent Switcher extension and set the user agent to Chrome or Edge on Windows 11.

It appears that Google has fixed this recaptcha issue for Windows Firefox users. You can change Firefox useragent back to the default if you did the temporary workaround by changing it with a useragant extension or by preference in about:config
