Cannot accede to backend page

[ThomasHg]

Hello,

Since this morning when I try to access the payment and carrier pages of the backend of my site I find myself in front of an error 500 which with the debug mode displays the following error.

So I guess it is an error coming from the "wic_eanupcgenerator" module however nothing happens when I modify the page in question and I cannot ask the developers of the module for help because they no longer do Prestashop.

In addition, the module is not yet installed on the site and if I delete the module folder from the FTP it does not change anything.

some help ?
