What browser are you using?
This is odd, I can't reproduce. Are you able to share a screenshot of the error in the browser console you're getting? You can also email me if it's easier (omar.sameh.shehata@gmail.com) or Discord (OmarShehata#1019).
Only thing I can think of is...I tried adding game analytics here. Maybe your browser is blocking that? Which is still a bug on our end because the game should still work without the analytics...
EDIT: does running in incognito work?
Yeah this is unfortunately the game analytics failing to load, and the game failing to start because of it.
I'm not sure why the analytics are failing to load for you, but the network tab may have more info on why that request is failing. I see here it's "ERR_BLOCKED_BY_CLIENT" which implies it's the ad blocker (is your ad blocker still running in incognito?)
