Got stuck

When I try to make a backup, I got stuck on 5%. “Building Package 5%”.
The log keeps saying something like “[25 May 15:47:24] DUP_PRO | 5a52fa3b | DUP_PRO_JSON_Entity_Base::get_by_id_and_type() | get_by_id_and_type: row SELECT * FROM wp_sfqdyb_duplicator_pro_entities WHERE id = 3 is null” al the time and never move on to other things.
