save preferences and restart Blender
do File > New > 2D Animation
try to draw something.

Since my 2D animation file is customized, I included it below.

Can confirm as well. In 2d animation file, object type is GPENCIL instead of GREASEPENCIL.
Maybe we'd need some versioning code to convert legacy grease pencil to GPv3 (it may be too early to add the versioning code though)

Grease pencil crashes blender on canvas click with pen or mouse (GP 3.0) #111279

Yes the crash is happening because we can't version the grease pencil objects yet. While the experimental option is selected, this specific crash is expected for now.

The crash can be avoided by loading the template, then going to object mode, then either using the operator search or the menu Convert > Grease Pencil. That will convert the object to the new type.
