Few Content Element not showing up for editing and few errors appearing

Hi,
After updating theme to latest version facing difficulties like many elements does not open for editing at the back end of the website. (Heading, Separator / Whitespace, Icon List, button).

It just shows empty white block or sometime it takes lot of time to load the block element for editing.

Thought some plugins might be causing this conflict and tried to disable all the plugins which was installed already, by doing so I got critical error and fixed it with the help of Host provider.

Now the website is up, enabled few plugins and content elements showing up sometime and not showing option for editing sometime, but still error pops up on the top of the page if we are in ‘Edit Advance Layout Builder’.

These were the few error which I copied for your reference.
