WPBakery Page Builder Plugin

Dears,

Whenever i try to edit a page, i have the error:
There has been a critical error on this website. Please check your site admin email inbox for instructions.

When i disable the plugin: WPBakery Page Builder Plugin,
the error is gone but i can’t edit the page properly.

I believe there is an update needed for the plugin.

What can i do to update the plugin or to fix this error.

wordpress version: 5.6
theme version: 1.20
WPBakery Page Builder Plugin version: 6.1
