Ursina version 7.0.0
Windows version 10.0.19045 Build 19045

Everything was working last week, one day I started encountering this error when I try to start any ursina script

Traceback (most recent call last):

AttributeError: module 'builtins' has no attribute 'loader'

Tried:

• running the basic ursina example scene
• running ursina in python's interactive shell
• reinstalling ursina
• creating fresh venv with different python versions (3.10, 3.11, 3.12)
• creating venv in WSL

all yield the same error message.

However, installing ursina 6.1.2 and running the basic example scene works fine.

Does anyone have an idea why this error occurs in the first place when it used to work perfectly fine? I installed ursina relatively recently so I would have most likely had the same 7.0.0 version.
