Sprite images generating process takes a long time and percentage hangs at 25%

Steps to reproduce:
{}1. Create a new project and install the "AI Generators" package
2. In the Project window, right-click -> Create -> 2D -> Generate Sprite
3. Enter any prompt and press “Generate” button
4. Observe the loading images

Actual results: Loading percentage increases and stops up to 25%, then suddenly jumps to 100% before generating the images
Expected results: Loading percentage increases up to 100%

Reproducible with versions: AI Generators 1.0.0-pre.6 (6000.2.0a10)

Tested on (OS): Ubuntu 22.04

Notes:

• The issue is not reproducible when generating Animation Clip, Audio Clip, Material or Texture 2D
