SMAPI failed to initialize。。。

I used language translation, but after smapi prompts that the game has not been started, but running game.exe directly can still start the game. I want to play games with mod. What should I do now?

 

I've got the same thing. Happened right after installing the 1.4 Stardew Valley patch through steam.

 

I am having the same issue. I have been playing since 1.4 update and today this started happening. I get the following error:

SMAPI failed to initialize: System.TypeInitializationException: The type initializer for 'StardewModdingAPI.Constants' threw an exception. ---> System.FormatException: The input '1.4.0.1' isn't a valid semantic version.

Game has ended. Press any key to exit.

The game has been working fine and this suddenly happened. I have uninstalled and reinstalled smapi. I have uninstalled and reinstalled Stardew. I have removed all mods. Smapi still brings this up regardless. The game will run if I don't run smapi. I play with my partner and they have no issues and our files are pretty much identical. Any ideas?

Update:

It appears that as I typed this they updated to smapi 3.0.1 and it works. Try to get a new version and hopefully it works.
