Plugin error

I can’t use WPBakery Page Builder with Uncode Theme when Contact Form 7 Plugin is activated: Every time I try to edit a block the only thing that appears is a loading circle that spins indefinitely. Also I see these network errors: net::ERR_EMPTY_RESPONSE and net::ERR_INCOMPLETE_CHUNKED_ENCODING

These behavior happens only when the plugin is activated.

Contact Form 7: Version 5.7.5.1

Uncode Theme: Version: 2.7.9

WordPress: Version 6.2
