Sprites has no preview in project/select window. unity2021.2.14-16

Hello everyone, I can’t see the previews when I choose the sprites recently. This has greatly increased my workload. Does anyone know what’s going on? What should I do? Unity 2021.2.16 HDRP.Thank you!


My problem has been solved, but I haven’t found the specific reason. I cut out all assets and their meta files batch by batch, run unity, and then copy them back. The problem is solved. It is unclear which asset caused it.
