Hi,

I'm currently having with some error that showed up after desinstalling some module.
When I'm trying to access any configuration page anywhere in odoo, it show this error:

TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'​

I understand the meaning of this error but I cannot find what could be source. If anyone has any ideas ...

Edit :

Here is the whole error:
