How to solve asset loading frustration when testing a game in Studio?

We are close to releasing a game with many assets (meshes, images, etc)…

Trying to test it in Studio with a 2 Player Test is next to impossible as most of the assets fail to load. We usually just get a long list of errors like these:

Image failed to load. Error 0: TooManyRequests - Studio

Is there anyway to get around this? It is very frustrating not being able to test properly.

The game works fine in regular studio ‘Play’ mode, and when published. But there are a lot of aspects that need this 2-Player test performed.
