incompatibility with Elementor and Plugins

Hello!
I create my site with OceanWP, but I have a lot of pproblems:
1) Elementos doesn’t work, it stays “loading…” and I can’t make changes. I discovered that I need to inactivate all my plugins to can use Elementor.
2) My plugin of WPForms doesn’t work
3) The message of “there has been a critical error on your website. Please check your site admin email inbox for instructions” appears ALL the time.

Please help, OceanWP is the only theme that has all the things that I need to create my website

Thank you in advice.
