Select sprite preview images not showing after upgrading to 2020.2.2f1

After upgrading my projects Unity version from 2020.1.17f1 to 2020.2.2.f1,

when I click target mark from source image in Image component,

select image panel show default icons instead of actual preview images.

Anyone experienced similar problem?

After Updating:

Same problem with Unity 2020.3.7f1 (64-bit)

Same problem in Unity 2020.3.7f1 (64-bit)

Exactly the same issue, very difficult to work without those previews, has anyone got a clue how to solve?

The same issue here makes sprite managing more difficult.

This issue has been fixed in 2020.3.16f1 (I noticed the problem also in 2020.3.15f2)

This is still the case in 2021.1.17
