LaggedStart not working

Im trying to use the LaggedStart() animation but i keep getting errors

Error message is: "object of type 'ShowCreation' has no len()"

`self.play(
LaggedStart(*[
ShowCreation(obj1, run_time=0.5),
ShowCreation(obj2, run_time=0.5),
Write(obj2, run_time=0.5)]
)
)`

The animations on their own work but i want then to start slighty after one another.

ive also tried without the array and also AnimationGroup() with lag_ratio=0.5 and the animations worked but they started at the exact same time

Look at the LaggedStart class in manim/animation/animation.py to understand how it processes animations. The error suggests ShowCreation objects are being treated incorrectly. Check the __len__ method or how animations are passed. Run the provided code snippet to reproduce the error, then examine the AnimationGroup and LaggedStart constructors.
