I have encountered the same issue. I had my website from months ago, and was using Elementor 3.23.x and everything was fine. Today I come to edit any page and I see this error.
I tried updating: No change.
I tried disabling all other component addons other than these, and still no change:
Elementor, Elementor Pro, PODs, SVG Support, Updraft Backup, Yoast SEO21:20
I am completely unable to edit my website now.
