Page Builder no longer works since update

Hi there,

Issues are:
1. Page Builder tab doesn’t appear on previously created pages (pages created before updating to latest WordPress). So I can no longer edit existing pages.

2. Add new page > Page Builder is there, but when I go to create a row and click “insert” nothing happens.

I have looked through a lot of support threads but with no luck in finding a solution.

I have tried updating plugins and WordPress again. Same issue persists.

I’m not a developer. So will need to get clear instructions.
