Fatal Error when installing

Hi, I’ve used this plugin on site I’ve built from scratch. And I loved it.
I am now trying to install it onto a site I am rebuilding, and I’m receiving this error when attempting to install it.

Please advise?

Fatal error: Uncaught Error: Class “BoldBlocks\Patterns” not found in /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php:257 Stack trace: #0 /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php(147): BoldBlocks\ContentBlocksBuilder->register_component(‘BoldBlocks\\Patt…’) #1 /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php(96): BoldBlocks\ContentBlocksBuilder->register_core_components() #2 /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php(77): BoldBlocks\ContentBlocksBuilder->initialize() #3 /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php(357): BoldBlocks\ContentBlocksBuilder::get_instance() #4 /nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php(361): BoldBlocks\boldblocks_cbb_get_instance() #5 /nas/content/live/bchp2stg/wp-admin/includes/plugin.php(2314): include_once(‘/nas/content/li…’) #6 /nas/content/live/bchp2stg/wp-admin/plugins.php(192): plugin_sandbox_scrape(‘content-blocks-…’) #7 {main} thrown in?/nas/content/live/bchp2stg/wp-content/plugins/content-blocks-builder/content-blocks-builder.php?on line?257
