Error after update today

I keep getting this

Fatal error: Cannot redeclare class fw_option_type_multi_select in /wp-content/plugins/unyson/framework/includes/option-types/multi-select/class-fw-option-type-multi-select.php on line 11

I tried changing fw_option_type_multi_select to fw_option_type_multi_selectx but I get the same error, just with it saying fw_option_type_multi_selectx cannot be redeclared.
