I don't see your picture. I also had to do the regular web.config change also (to allow unityweb files to download). In addition, I had to turn off gzip compression. And set the memory size to 256. And turn off WebAssembly. Its possible that the resources won't load because the memory is not large enough. Having a lot of configurable parts can be quite a memory hog. First step is to go into the global library, and remove the items you don't want. Probably the easiest thing is to just delete them from the project, and then repair the global library. A lot of the textures in UMA can be very large also. You may want to manually change them so they are smaller. The face/body/eyes should probably remain the same unless you want to adjust the rectangles for the various overlays, though. SlotDataAssets can be large also. They hold all the mesh data. If you delete slots/overlays/textures, be sure to delete any wardrobe recipes that use them so you don't get an error.
