There are many possible causes for this error, but the most common reason is the use of mods. Mods can sometimes conflict with the game or with each other, leading to loading issues or crashes.

To troubleshoot this, please remove all mods from the game and start a new savegame to test whether the game loads correctly without any modifications.

Additionally, please ensure that your Internet connection is stable. Unstable or weak connections—especially mobile or public Wi-Fi networks—can cause problems with game verification or loading. Please note that mobile hotspot connections are not officially supported.

Make sure your graphics drivers and operating system are fully up to date. In some cases, background software such as antivirus programs or firewalls can also interfere with the game’s startup—try disabling them temporarily to test.

If the game still does not load after trying all of the above, please contact our customer service and include as much detail as possible, such as your platform, any error messages, and the log.txt file located in:
Documents > My Games > FarmingSimulator20XX > log.txt (replace "20XX" with your version).
