I have checked the server error logs and found that SEO plugin generates the fatal error and then memory limit error appears that caused issue with the Elementor plugin loading https://prnt.sc/X5Nx1o-_1Q_c
If you disable the theme you just reduce using of the PHP memory but it does not solve the fatal error that comes from SEO plugin. So, could you, please, ask plugin developers to take a look at that error, and fix that. Also, check the list of plugins that you use. You have 52 active plugins. Please, disable plugins that you don’t really need because every additional plugin uses PHP memory and you have problems with that.
