Error message when creating invoice

Hi,

I’m receiving an error when I try to create an invoice. WordPress did send the e-mail below. I tried downgrading my php version to 8.0 and also 7.4 but this did not solve the problem. Hope you can help me out finding a solution.

WordPress versie 5.9.2
Huidig thema: Soap7 custom made theme
Huidige plugin: Invoices for WooCommerce (versie 3.1.9) PHP versie 8.1.3
