godot Scene re-import crashes

Godot version

4.0-git (1e3919c409)

System information

Fedora 36

Issue description

Working on a project for a long time with Godot 4, I have some imported scenes from some time ago. As I attempted to reimport some scene due to changing some import setting, the editor fails to show the advanced import settings window and crashes instead.

ERROR: FATAL: Condition "!exists" is true.
   at: operator[] (./core/templates/hash_map.h:504)

Steps to reproduce

Open the MRP and double click on the imported cube scene.

Minimal reproduction project

MRP.zip This minimal reproduction project was made with Godot 4 beta5 and it should crash with any latest Godot when you open the advanced import settings of the cube scene.
