We'll need to see the output_log.txt (called player.log on Mac and Linux) to see what's causing it. Here's where to find the log depending on your operating system. To easily find the local files for the game, right click your game in the Steam library, select Properties, go to the Local Files tab and select Browse local files.

Windows
\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt

Mac OS X
Users//Library/Logs/Unity/Player.log

Linux
~/.config/unity3d/Colossal Order/Cities: Skylines/Player.log

As we can't attach files here on Steam, you will need to upload the file somewhere else. Here's a few sites you can upload it to, which do not require you to sign up first:

Firstly please do NOT copy paste logs in posts here. They are way too long to fit in a response. :)

Now for your issue. You're running out of RAM, and you already have a 32 GB pagefile that's full. In that case you should really remove some workshop assets. You have more than your system can handle.

For 8 GB of RAM I recommend you tr... Read more

Looks like something related to a transport line or public transport vehicle. Let's try using the Loading Screen Mod's Safe Mode options. Before loading your save, go into Options and find the Loading Screen Mod on the left. Then find the Safe Mode options and enable all of them. Then load your save. Did that help?

Check your storages, they are probably full or close to full with all trucks busy exporting. You need more storage until you have at least a few of each type set to Balanced, that do not get full and always have a handful of trucks available.

Did you manually move the files? Or did you have Steam move the game?

Are you using any mods? Most mods are designed for the simulation and break things in the editors. For that reason it's always best to disable all mods you don't absolutely need when doing anything in the editors.

If you don't need any mods, you can easily disable them all with the -disableMods launch option in Steam.

Sounds like you don't see the launcher at all. Try reinstalling it following these steps:
https://steamcommunity.com/app/255710/discussions/0/1742265315844206043/

This is usually a Steam connection issue. Log out of Steam, shut it down completely, restart Steam and log back in. That usually forces it to connect properly.

Since Steam doesn't show you as owning the game, I'm gonna take a wild guess and assume you got it on Epic. In that case please update your video driver from the vendor's website.

IF that doesn't help also go here:
https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
And run the x86 and x64 installers there.

Are we talking about a custom map you made yourself? Or does it also happen with default maps?

I recommend a much larger pagefile and it's better to not split it. With 64 GB of RAM I'd set it to at least 64 GB, but you can go for 128 GB just fine. Just make sure it's on a drive that has that much free space.

I also think it’s not the mods. I removed the suggested ones and did not fix the problem.
I will follow your advice and redo all bus transport lines. But what I don't understand is how long bus lines can interfere with metro lines, for example, they are also failing or disappearing. So it is with monorails and trains. I have even remade the city's three line replaced by subway, and I left it for cargo only.
So I think it is something bigger than the complexity of the bus lines.
Thanks also for indicating the tutorials, I will watch.

Metro (and train) lines usually fail because of too sharp angles. Since Sunset Harbor we can't have sharp turns for... Read more

First thing to figure out is if it's related to mods/assets. To do that add the launch options -noWorkshop and -disableMods then start a new city to test. You don't have to build anything, we just need to see if it saves properly.

How To Set Launch Options

• Right-click on the game title under the Library in Steam and select Properties.
  
• Under the General tab click the Set launch options... button.
  
• Enter the launch options you wish to apply (be sure to separate each code with a space) and click OK. Should look like this:
  -noWorkshop -disableMods
• Close the game's Properties window and launch the game.

First things first. I really recommend you save manually, and make a new save each time. This one is an autosave, and it's never great to have that be your main and only save. I add a number at the end each time I save, so I have CityName1, CityName2, CityName3 and so on.

I don't think this is a mod issue, I think it's the way the roads and lines are set up. You have some very long and complicated transport lines, and as far as I can tell, they're the ones that are broken. In trying to fix one, I came across this green line:

Notice how it's going all over the place on the highway? It's getting trapped in all the one way roads trying to get to the next stop. It's not ideal and I get confused just looking at that image, trying to track down where it's going. :P

I would redesign the lines having ... Read more

In Options under Gameplay there's an option to turn off "auto-open Chirper messages"

It uploaded as it should. Here's the link. :)

I'll take a look and see what I find :)

Set up a custom sized pagefile of 32 GB (that's 32000 MB since pagefiles are measured in MB). That should do the trick. Here's a guide that explains how. :)

If you can post your savegame, we might be able to see what's happening. To do that, go to the Content Manager, find Savegames on the left, find your save and click Share. Then give it a name and a description if you'd like, click Upload and copy the url of the page that opens. Post that here and we'll be able to download the save ourselves. :)
