critical error with TwentyTwentyFour theme

I uploaded the Twenty twenty four theme to my wordpress.com with business plan. It worked fine yesterday, but this morning, the site itself was fine, but when in the admin panel, I can’t access posts, editor etc. I get a whte page with the following:

There has been a critical error on this website. Please check your site admin email inbox for instructions.

I’ve checked my email and I don’t have any instructions. I followed the trouble shooting guide, and switched back to twenty twenty three theme and everything is working fine, so I think it is the theme. I still want to use 2024. What can I do to make it work?
