Wordpress Theme and plugin Errors

Hello. We are using the Brisk - Multi-Purpose Elementor WordPress Theme and the UiCore Framework in Wordpress and the Elementor editing tool is crashing.

So we are advised to update the Brisk Theme and UiCore plugin but we are getting errors installing the UiCore plugin.

I am getting most advise from developers that we need to stop using Brisk and get a new theme and redesign our entire website, but I am doubting this. I believe this error can be fixed.

Please respond if you think you can fix this problem.

We are hosting at WPengine
