Wordpress 5.9 Blank White Screen with Edit Post/New Post (Cheer Up Theme)

My Wordpress got automatically updated to 5.9 with the Cheer Up theme, and I get a blank white screen every time I go to edit a post or add a new post.

I have gone into troubleshooting mode and disabled and enabled every plugin with their Twenty-Twenty theme, and I am able to edit posts that way.

Are there any fixes you have for this theme so I can continue to edit and add new posts?

Thank you.
