You may get this error while processing certain images in Gigapixel AI.
Especially images exported from Photoshop 2020.
If you have Photoshop:
1. Open the image that is causing the crashing in Gigapixel AI in Photoshop
2. File -> Export -> Export As
2. Make sure that when you export, you export with Metadata set to None, and make sure that "Embed Color Profile" is not checked.
If you do not have Photoshop please re export your image with the meta data and color profile data removed and try running your image in Gigapixel AI again.
