In one of my projects, the asset store will only show a blank window and Line Renderers are always white no matter what color I choose.
Solved. The 2 issues were unrelated. I must have accidentally changed the Line Renderer’s color and the store finally fixed itself after restarting Unity a few times.
I have a similar problem. My asset store windows is just as blank. I tried restarting Unity, I tried rebooting my computer. Just stays blank. I had the problem a couple weeks ago, and it eventually came good after a few days.
However, it is very frustrating not being to get it to work. I need to login to a browser, find the asset I want to import, and then do a search in the Project tab to find the asset, and import it from the inspector.
I have googled, but cannot find a reliable fix for this.
