Generate is Disabled When Opening a Blend File

[NullSenseStudio]

Description

Generating any image is disabled when opening a .blend file, starting Blender directly and then using its File > Open... alternatively does not. Releasing the generator doesn't help.

The console gets spammed with 'str' object has no attribute 'model_type'. I've tracked this down to

dream-textures/ui/panels/dream_texture.py

Lines 368 to 369 in 4f210c5

	except Exception as e:
	print(e)

This actual error is occurring here

dream-textures/diffusers_backend.py

Lines 263 to 268 in 4f210c5

	def validate(self, arguments: GenerationArguments):
	model = model_lookup.get(arguments.model.id)
	if model is None:
	raise FixItError("No model selected.", FixItError.ChangeProperty("model"))
	else:
	if not model.model_type.matches_task(arguments.task):

For some reason model_lookup is not being updated and just returns the model id string.

It can be made to update by installing another model: either downloading, importing, or linking.

Steps to Reproduce

1. open Blender and save a new .blend file
2. close Blender
3. open .blend file from file explorer (NOT from within Blender File > Open... / File > Open Recent)

Expected Behavior

Generate button to not be disabled.
