Hello everyone, i've installed a custom module in my odoo 15 server, the module is "Odoo 15 Full Accounting Kit" by CYBROCYS, i want to uninstall it because i got some issues in other modules, but when  i click uninstall i got this:

Traceback (most recent call last):
  File "/opt/odoo15/odoo/odoo/api.py", line 886, in get
    return field_cache[record._ids[0]]
KeyError: 

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/odoo15/odoo/odoo/fields.py", line 1082, in __get__
    value = env.cache.get(record, self)
  File "/opt/odoo15/odoo/odoo/api.py", line 889, in get
    raise CacheMiss(record, field)
odoo.exceptions.CacheMiss: 'ir.model(,).count'

The above exception was the direct cause of the following exception:

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
