fh_unit.gd
line 171, attempting to add a line here (and eventually comment out those below...) causes the crash when intellisense tries to load methods etc (I assume!)

Confirmed the test case. Beta4 is fine. Master (afe1c89) is not. Win 11/64.

It's not just NavigationAgent3D. I encounter this typing player.mesh. referring to the scene that holds a large mesh. I would change the title to just Crash on autocompletion.

Bisecting reveals both this and my issue were caused by.... 65d1467
#68663 Fix completion popup for the variables created with get_node call
@Chaosus

Needs tags, milestone.

This is also probably a duplicate of #68901, but this has a simpler test case. I did not test the other.
