Update 9.0.0 to 9.0.1 - Erreur DB_ERROR_2006

Hello,
I updated dolibarr to version 9.0.1 (shared server installation) and when migrating the database I get these three errors.

Erreur DB_ERROR_2006: DELETE from llx_accounting_account where rowid in (select minid from tmp_llx_accouting_account where minid NOT IN (SELECT fk_code_ventilation from llx_facturedet) AND minid NOT IN (SELECT fk_code_ventilation from llx_facture_fourn_det) AND minid NOT IN (SELECT fk_code_ventilation from llx_expensereport_det));

Hello,

Thank you for your reply.
I am on a shared OVH server and I do not have access to this configuration.
Do you know any other way around this error?
Thank you.
