#15353uv env instability

Summary

I want to report an issue with uv environment, I'm encountering the issue with click and customtkinter, but let me use the latter to describe it here

Hey experts,

When I import the customtkinter package, I get the following error

Traceback (most recent call last):
  File "/Users/wbenzid/Projects/mwareeth/mwareeth.py", line 9, in <module>
    from gui.app import MwareethApp
  File "/Users/wbenzid/Projects/mwareeth/gui/app.py", line 10, in <module>
    import customtkinter as ctk
  File "/Users/wbenzid/Projects/mwareeth/.venv/lib/python3.12/site-packages/customtkinter/__init__.py", line 22, in <module>
    from .windows import ctk_tk
  File "/Users/wbenzid/Projects/mwareeth/.venv/lib/python3.12/site-packages/customtkinter/windows/ctk_tk.py", line 10, in <module>
    from .widgets.scaling import CTkScalingBaseClass
ImportError: cannot import name 'CTkScalingBaseClass' from 'customtkinter.windows.widgets.scaling' (/Users/wbenzid/Projects/mwareeth/.venv/lib/python3.12/site-packages/customtkinter/windows/widgets/scaling/__init__.py)
make: *** [run] Error 1

If I run uv remove, then uv add it get fixed

After sometime the env get corrupted while I didn't install or remove any new package

This is the output of uv tree
