Elementor won't load

I had an up and running and complete site and Elementor was working fine.
Today I decided I want to delete all WP files and remake my whole site again. I installed the latest version of WP, my theme, and all plugins but Elementor doesn't work. I tried downgrading wp and Elementor, all the fixes I found on the internet, I tried reinstalling and installing WP and checking incompatibility with plugins and themes but everything was okay and nothing helped. Elementor is just stuck on loading and the safe mode says "an error occurred" I also tried editing in different browsers, different wifi connections but nothing helped.

note* Elementor is working fine on my other site but not on this one

Can you please help me resolve this?
Thank you in advance.
