Failing to Load Multiatlases in Chrome Incognito Mode on Low-End Tablet

Hi, all. I’m creating a project for a very low-end tablet (specifically this one: https://smile.amazon.com/PBS-KIDS-PBSKD12-Playtime-Marshmallow/dp/B01MDLUWTO/ref=cm_cr_arp_d_product_top?ie=UTF8), and I find that when I run the game in Incognito Mode in Chrome on that tablet, after a while, I start seeing the green/black box that indicates a texture failed to load.
I got remote debugging in Chrome set up, and I found these error messages at the console, indicating that, indeed, something failed to load, specifically in XHRLoader.js.


Has anyone run into something like this before? This happens when I go into a certain scene after creating it on the fly and destroying the previous one, so there shouldn’t be any textures hanging around taking up space in RAM unnecessarily.
Any guidance would be greatly appreciated! Even if you’ve never run into this specifically, maybe conversing about it will point me in the right direction.
