I have the same issue. So at first I tried to load the tree lot (live mode) with mods activated, and it got endless loading. I deactivated mods and tried the tree lot again, but same thing. At that time, I thought the error might be related to the tree lot. I booted the game up with mods disabled once more and loaded another household, and for some reason it worked. I tried another household that also worked - although I don't know if both household was the same neighborhood. Also, the first household MIGHT have been in another neighborhood, before I exited to manage world and tried the other.
Then I moved the household from the tree lot to another in the same neighborhood and loaded that lot - which worked. So after that I entered the tree lot in build mode and it also worked. I bulldozed the lot and moved back my household/person that lived there in the first place. Now it worked. I did not save after that, since the sim would loose all her cc (since it was not activated).
I then booted up the game with mods and moved the sim to the other household in Everdew. Tried loading that, and endless loading. Booted the game up once more and tried to go directly to build mode on the tree lot: endless loading. After that I booted the game up with mods disabled again, and suddenly the other household in Everdew once again got endless loading. I even tried to load a previous save file, but get endless loading on that as well in Everdew. The few times it worked seemed to be some kind of fluke. I heard from someone that it could be related to DX9/11. I will have to check with DX. I think I have chosen dx9 ingame but when I look into log files, it says dx11?
Also, I did get some last exception, but in text format (notepad). Mc conmand did not generate anything
