[2022] HELP... Problems since Airports.

First thing to check is whether this also happens when you add the launch options -noWorkshop and -disableMods and test on a new city.

If that works just fine, then it's likely either a memory-related problem or it's a mod incompatibility. Let us know if it works fine with the launch options and we'll take it from there. :)

How To Set Launch Options

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