there is a log: https://log.smapi.io/BcvW7AGk

Hi @netcan. That error is happening in .NET Framework (not SMAPI), and usually means something is wrong with your computer's memory. I suggest running memtest to check for hardware issues.

I have solved it by reinstalling XNA framework: https://www.microsoft.com/en-us/download/details.aspx?id=20914, I found that it has different size from game's.
