critical error on this website

Hi,

I have been adviced to post my message in this forum section, so hopefully you’ll be able to help me (fingers crossed!)

This was/is my original message posted:
Hi! I received the following message on a couple of my WordPress pages:
There has been a critical error on this website….

After not being able to log in to my website, I contacted my hosting company and luckily they could set the pages back to a previous backup. They told me that it had to do with the ELEMENTOR plugin….
I wanted to ask, do I disable this plugin? If I do so, will I loose all pages I created with Elementor?
I do not want to uninstall and later find out I have to create all those pages again 🙁
The pages I created with WOOCOMMERCE are still working, all other get this critical message!

Kindly advise what to do. Please know that I am the website builder, I do not have a company helping me and I do not know anything about the ‘backend part of a website

I hope you will be able to help me 🙂

Regards,
Rose`
