Why the prefabs loose their preview in the Project windows ?
Suddenly all the prefab of my project loose their preview icon, replaced with a blue cube.
I could instansiate the prefab in the scene then drag them in the Project windows to recover the preview image. But i don't know if they gonna loose again the icon..
Is there anyway to be sure they don't loose the preview again ?
Even if they are send in a custom package ?
Thanks for any reply !)

Having the same problem today. It was caused because I moved the folder after importing. Solution: right click on the prefabs window an select "Reimport".

Anyway to fix the prefabs if they all go black? I've tried reimporting
According to https://answers.unity.com/questions/1689301/all-asset-previews-for-prefabs-and-models-are-full.html, disabling and reenabling the mesh renderer may resolve this.
