I can not see a preview of my materials or objects

So, yeah… i can not see the preview of my materials in the inspector. In order to see it i have to click each material but that doesn’t help at all…

Here is how that folder looks in the editor in 2021 LTS

Here is how it looks in Unity 6…21.f1

I can even see previews of my objects either

I need to see those previews in the editor, i can’t waste time clicking on each one, i also already tried the “import” and “refresh” options.
Maybe it has something to do with the following annoying error that i can get rid of it and yes i already saw that other post and is not working either:
The error is:
Unexpected transport error from import worker 42. code=10054 error=An existing connection was forcibly closed by the remote host.

Try to select them all, right click, re-import. Usually that fixes my previews for Prefabs, but might also fix materials.

Hi, that was a good idea, sadly it didn’t worked, also “Refresh” didn’t worked either

Hi I have the same error and to date I have not solved it, I delete the library and it works for 10 minutes and from there it comes back again

Well i updated to the latest version and it is working but it still have a little bit annoying bug i’m going to create another topic for that…
