Short description of error
I was following this tutorial: https://www.youtube.com/watch?v=g7EGSCo1YBI
when i was reproducing the steps at 18:50 adding an atribute fill node and change the type to color, when i click the square to change the color value, blender crashes to desktop.
Exact steps for others to reproduce the error

with blender open, add geometry nodes to the default cube;
split screen and change to geometry node editor;
add atribute fill node, change attribute fill node type from float to color;
click on the rounded square by the value to change the color. it made my blender crash.

[Based on the default startup or an attached .blend file (as simple as possible)]
