GDScript Texture Import Causes Crashing in Godot v4.0

[MrJoshBowman]

Godot version:
v4.0.dev.calinou.5953f4d76

OS/device including version:
Macbook Pro 16" (2019), MacOS Big Sur v11.2.2, AMD Radeon Pro 5500M (Vulkan) if graphics-related. -->

Issue description:

• set up a button to import texture to 3D model
• works the first time
• on the second time clicking the button and importing a texture the test crashes and outputs this in the debug:
  

...and an aside...not sure if this is linked or not... but in my main scene I keep getting this error if I'm in the 2D window:

This 2nd error seems to happen because I haven't set my Control2D nodes to be larger than 0,0 initially, which i do later with code. This error didn't happen in Godot 3.3

Steps to reproduce:
I've attached a file that reproduces the main error (not the aside).
This error does not occur in Godot v3.3 with the same setup.

Minimal reproduction project:
11_TextureTest.zip

This error spam is a known issue (which needs to be fixed on our end), see #45911 and #45746.

Seems fixed in alpha 8, can someone confirm? Not sure how to test it exactly.

EDIT:
Ok I think the project is supposed to crash after launch, which isn't happening. Closing, comment if you can still reproduce.
