Fixing a bug with the WordPress Elementor Pro and performance issues.

Okay, we have a client who is having a problem with Elementor Pro. He says that when he tries to edit using the app, it tells him that he must enter Safe Mode. However, if he enters Safe Mode, he can't edit anything—neither the images, nor the text, or anything like that. We tried to implement a small fix, but that fix seemingly messed up other things. So, we need someone who is very skilled in Elementor Pro to fix this bug. Additionally, we have a problem with the application's performance, and we suspect there might be a security breach or some network-related issue. Therefore, we might also need someone to check the WordPress project overall.
