I loaded it in just fine. No errors. Likely a memory issue. The game uses a lot of memory and it will offload a lot of it to your Window's virtual memory, to free up RAM. The problem is Windows chokes on it one the page file is roughly the same size as RAM, and choke and possibly crash.

I noticed you didn't have the Loading Screen Mod installed, which optimizes assets inj the game and it can save 5% to 20% of memory.

If this doesn't work, then you need to increase page file size to double your RAM or so. (1.5 times RAM minimum)

This is a decent guide from Steam:

Your whole mods/assets lists are built into you saved game.

From "Content Manager" you can go to "Savegames" and scroll down to your city and click "subscribe all", and when that finishes, click "Enable All;" and it will Disable all content that was disabled and enable all workshop that was enabled at last saved game.

Then you should be able to load your save game with all of your workshop.
