Unable to move components within a form

Hi there!

We are using Retool self-hosted version 3.33.20-stable and are running into an issue with forms. I was initially able to create a form with various inputs and UI components, and everything works. However, I am now unable to move or add components within the form. I can move components from inside the form to outside, and I can add and move components outside the form as usual.

This is only happening in this specific module, which makes me think that this module has somehow gotten into a bad state (other forms in other apps are fine).

I've tried disabling all browser extensions (I am using Arc version 1.40.0), force-refreshing the page, clearing the cache, cookies, etc. This also happens to me in Google Chrome and Brave. I am able to make changes by exporting it to ToolScript, making edits, and then importing from ToolScript, but that's very cumbersome.

I've taken a screen capture and I can post the exported module as well.

Here's a link to the screen recording: Screen Recording 2024-05-03 at 1.20.17 PM.mov - Google Drive
