to_preferred brakes REPL

[nopria]

I'm not able anymore (I was some months ago) to use "to_preferred" method.

Here are the steps followed to create a new environment: (I was not able to install mip through conda, so I had to install it with pip -- I'm in WIndows 11)

conda create -n appbis python
activate appbis
conda install conda-forge::pint
pip install mip --user

Getting into Python REPL:

>>> import pint
>>> um = pint.get_application_registry() # need this to avoid errors due to using different registries
>>> um.default_format = "~P"
>>>
>>> q=3*um.kN/um.cm
>>> q
<Quantity(3.0, 'kilonewton / centimeter')>
>>> q.to_preferred([um.kN,um.m])

and I'm kicked out from REPL without errors nor message of any type.

Here is the packages in environment appbis:

[andrewgsavage]

have you tried any other mip versions?

[nopria]

No, should I? Which version should I try?
