Erro crítico após atualização

Após a atualização, notamos erro crítico no WooCommerce, na listagem de pedidos, conforme imagem: https://ibb.co/Dt9cWP2 . Notamos que, se formos em opção de tela e removermos a opção de ver status do pedido, o erro não ocorre.

Segue o log, troquei o número do pedido por XXXXX:
