The use of Elementor on Free hosting is discouraged because of how many resources it consumes, which also leads to quicker suspensions.
Yes. Remove Elementor. And generally, there’s nothing an administrator can do because it’s your website, and you must adhere to the limits, one of which is trying to solve your own problems. But, whatever you do, don’t just willy-nilly add plug-ins! it’ll only make the problem worse doing so.
If removing Elementor doesn’t help, maybe try reinstalling WordPress.
