[2020] Can't load my city if I change the settings of Loading Screen Mod

Hmm, for some reason there's no crash in that log, so we can't be 100% sure. But I'd definitely expect the crash to be from running out of memory. With 16 GB of RAM, you should expect to be able to have 800-1200 assets if you have no DLCs. Any more than that would be handled by your pagefile, and once that's exceeded, the game will crash.
