Elementor and Astra Pro

I just created a new site using Astra, I also have Astra Pro. If I turn on Elementor I can no longer edit a page and save. I use Astra and Elementor on all my pages and this has never happened. Any ideas?

When I click edit with Elementor from the Page menu it times out and wants to go to Safe Mode (which it won’t do). if I do a standard edit and change anything it says ‘Updating Failed’.

Please help,
