Please explain your issue is in as much detail as possible.
When loading my saved game, it turns into a blue screen. 7/8 of the screen is blue. And then it freezes.
I have tried to disable all my mods, but without any luck. I also removed all assets, which I cannot use due to missing DLC's.

When I start a new game, I don't get any issues.

Can you replicate the issue? If yes, please explain how you did it.
Yes, but only by loading the screen.

Update:

I am playing this map: Seahorse Islands v2

It works on the games regular maps with all mods listed above.
However I just tried with a downloaded map: Portage
This crashed too, but with brown screen. See attached.

You have a few buildings that fail due to a missing network. Make sure you're subscribed to this network and that it's enabled in the content manager.

Steam Workshop::Curb Network

If that doesn't help, add the mod SafeNets, enable it and restart the game. Then, before loading your save, go into Options, find the Loading Screen Mod on the left and enable the Safe Mode options. Then load your city.

If none of that helped, please attach a new output_log.txt from the last attempt.
