Bug White Sprites used in UI Toolkit in Build (because of Sprite Packer), missing Texture...

I couldn't reproduce it in a separate project, but after upgrading from 2022.1.13f1 to 2022.2.0b8 Sprites that were used in UI Toolkit appeared white in Build:

At first I thought maybe Sprite's meta needs to be regenerated, but no, this didn't help (removing and recreating Library didn't help too).
Only moving sprite to Assets/ helps, but I can't reproduce it in a new project - there's no issue with sprite location.
Then my colleague found that it's related to Sprite Packer. Using Sprite Atlas V1 - Always Enabled it could also be reproduced in Editor

Another issue was missing texture that was used in Shader Graph.
The same happens in b9

I also tried latest Alpha and there was no issue with white Sprites there.
