Error after renaming components

Hi.
In a project in the App Inventor2, with 2 screens, which were running normally, after I renamed some components, in screen2, it no longer mounted, leaving the screen white. And when I go to the public and order some to be executed, it is giving an error. What can it be?

Try reloading everything, browser, AI2, companion app.

Thank you for answering, TIMAI2. I didn't actually restart these items. I closed all of them and turned off the PC, and I'm testing it now, and the situation continues, and only for screen 2.

Try using the latest updated companion (which is under testing)

Is this.

PS: I'm using the "HorizontalArrangementAddons.aix" Extension, did this one have any problems?

Have you updated to companion app v2.73ad2 as provided in the link above ?

No, it is returning this information from the figure.
Yesterday, I uninstalled the extension and screen2 reappeared, without giving the error I mentioned.
It may be that the extension is not compatible with the version I have of the companion.
For information purposes, since I don't know if it proceeds, before renaming the components, I had changed the user interface to "NEO", I made some changes and then went back to the "CLASSIC" interface a few days later.
