Resources failed to load

How to fix this? Usually it fixes when I reload the page but it didn’t when I reloaded it.

Hi
I reported this to the devs, this is in the resource list right?

There is just a miss on the icons or the models aren’t visible in the preview?

let me see if it appears on preview

Yes, it’s just the icons and when I tried exporting, it said it failed downloading the resources and it is the items that icon wouldn’t load. The cars are 3D
