Critical error

Hi,
I get an critical error after importing a CPT from another site.
I have uninstalled Metabox plugins (main + AIO) and reinstalled them.
The error is still triggered when I try to create a new CPT.
The imported CPT doesn't appear in the CPTs so I can't delete it.

Here is the error:
Fatal error: Uncaught Error: Class "RWMB_Update_Option" not found in C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-content\plugins\meta-box-aio\vendor\meta-box\mb-custom-post-type\src\Edit.php:111 Stack trace: #0 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-content\plugins\meta-box-aio\vendor\meta-box\mb-custom-post-type\src\Edit.php(24): MBCPT\Edit->is_premium_user() #1 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-includes\class-wp-hook.php(310): MBCPT\Edit->register_upgrade_meta_box('mb-post-type') #2 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-includes\class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #3 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-includes\plugin.php(517): WP_Hook->do_action(Array) #4 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-admin\includes\meta-boxes.php(1701): do_action('add_meta_boxes', 'mb-post-type', Object(WP_Post)) #5 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-admin\edit-form-advanced.php(271): register_and_do_post_meta_boxes(Object(WP_Post)) #6 C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-admin\post-new.php(75): require('C:\\Users\\Jo.DES...') #7 {main} thrown in C:\Users\Jo.DESKTOP-U3C5KT0\Local Sites\blueprint\app\public\wp-content\plugins\meta-box-aio\vendor\meta-box\mb-custom-post-type\src\Edit.php on line 111
