Update I used this snippet, which resolved the issue on my site, may be helpful for anyone who faces the same issue.

/**

• Description: Patches three bugs in class-wcfm-stripe-connect-client.php.
• Bug 1 & 2: On PHP 8, get_user_meta() returns an empty string when
• the wcfmmp_profile_settings meta key does not yet exist for a vendor.
• WCFM then attempts array offset access on that string which is a fatal
• TypeError in PHP 8. This fix ensures the meta is always initialised as
• an array before WCFM processes any Stripe connect or disconnect action.
• Bug 3: If create_account() fails and returns null during a connect type
• switch, WCFM immediately accesses ->id on the null return value causing
• a fatal error on any PHP version. This fix guards against a null account
• being passed into the account links args.

// Fix 1 & 2: Ensure wcfmmp_profile_settings is always an array before Stripe connect/disconnect
add_action( ‘template_redirect’, function() {
if ( isset( $_GET[‘stripe_action’] ) ) {
$user_id = get_current_user_id();
if ( $user_id ) {
$vendor_data = get_user_meta( $user_id, ‘wcfmmp_profile_settings’, true );
if ( ! is_array( $vendor_data ) ) {
update_user_meta( $user_id, ‘wcfmmp_profile_settings’, array() );
}
}
}
});

// Fix 3: Guard against null account in create_account_link
add_filter( ‘wcfm_stripe_account_links_args’, function( $params ) {
if ( isset( $params[‘account’] ) && is_null( $params[‘account’] ) ) {
$params[‘account’] = ”;
}
return $params;
});
