Object reference not set to an instance of an object

[Jeremy_F]

Since I was updated to the new editor more than 30 hours ago, I keep seeing the error “Object reference not set to an instance of an object.”

I was regenerating a table, when the update was rolled out.

Whenever I try to regenerate a table, I stop seeing the option to edit its columns or view its data.

I have managed to restore the app to an old working version, but

1. Changes in App expressions don’t work in the app
2. Formatting rules work without any issues

Even if the app(old version) works, the error is still displayed in the editor - “Object reference not set to an instance of an object.”
