I don’t get the network error but I can see that you are making 944 requests at once
Which is a lot and I can see why on some machines, this could lead to the issues you’ve mentioned.
In general, you need to reduce the number of network requests that you are requesting at once.
Some ways to help with that:
Use a in game loading screen(s) and load groups of assets at at time (eg groups of 200) and/or load them when needed for the next screen/part of the app. A bit more information here: Optimizing Load Time | Learn PlayCanvas
You can do both options too as I noticed it’s a 120MB download before the game really starts. I would advise on how to make the initial loading time as short as possible as the user generally leaves after 3-4 secs of loading
