Blocks page is not loading, blank!

The situation occurred from noon today. When I switch to “Blocks”, they do not display anything. I have tried all browsers, incognito mode, etc., but it is not working.

@01234trieuda23koaz Thanks for reaching out about this.

Usually this behavior is caused by an error in the blocks themselves–I have made a copy of your app and am able to open it with no issues. I will send you the link to that copy in your messages.

Thank you so much. You’re a lifesaver. However, my “A” screen is still blank (in the Blocks section), while the other screens are fine. (#Before the error, the “A” screen was still able to enter Blocks!)
