Summary​

After updating to version 1.3.3f1 (1166.34240) [5841.24389], a critical error continuously occurs upon the first launch of the game.

Steps to reproduce​

At first, I wasn’t even aware that there had been an update. I launched the game and stepped away for a while, only to return and find that it had updated to a new version. However, the main menu was extremely sluggish. Upon realizing the game had been updated, I suspected there might be a conflict with some mods.

Using Skyve, I checked for potentially problematic mods and began unsubscribing from them one by one in-game. Despite this effort, the issue remained unresolved. Based on the message [critical] system update error during Prefabupdate -> meshsystem, I suspected that something had gone wrong during the update process itself, and decided to reinstall the game.

After reinstalling, I launched the game again, but the issue persisted. Just in case, I tried running the game with the -disableModding launch option, unsubscribed from Skyve as well, deleted the active playset, and created a new one. I tried several different approaches, but the error message continued to appear, and none of the assets from the newly updated DLC were displayed correctly in-game.

Determined to resolve the issue, I decided to perform another reinstallation. This time, I unsubscribed from all mods and reinstalled the game from scratch. Unfortunately, this still did not resolve the problem.

While browsing the forums, I found a suggestion to rename the Cities Skylines II folder located in the AppData directory, thereby launching the game in a clean state. I tried this as well, but it had no effect.

Expected Result​

I had hoped that all issues would be resolved; however, for some reason, the assets from the new DLC continued to be missing, and I was unable to find a solution to the problem.

Actual Result​

Upon the first launch of the game, a critical error message appears, and the update news window shows no content. Additionally, when starting a new game, none of the assets related to the new DLC are visible in the menu. This issue affects not only roads but also parks and new buildings.

Game Version​

1.3.3f1 (1166.34240) [5841.24389]

What mods do you have installed?​

Initially, there were a few mods installed, but I performed a total of three reinstallations, and from the second reinstallation onward, all mods had been unsubscribed.

I deleted the game folder from Steam as well as the folders in AppData and reinstalled the game, but the issue still wasn't resolved.

Please log into the launcher before starting the game from it. Attach a new log if there's still a problem, thanks.


\AppData\LocalLow\Colossal Order\Cities Skylines II ain't bringing up nothing, chief
It is there for sure! In File Explorer click on Local Disk C:, Users, your user name, AppData, and so on down that path.
 
Maybe same question
