how can I fix this issue? please help

Can you give more context? While, when this happened? What SMAPI version you are using? What mods? What were you doing with teh game when this happened?

Looking just at this screenshot I have no idea what I am looking at, to be honest, and I wanna help :)

@dvdhaliem I have a feeling your graphics drivers are out of date, because that looks like corruption.

@speeder I'm using SMAPI 0.37.2, that happend when a few minutes I play with CJBCheatsmenu mods. But when I turn off that mods and play with SMAPI, my game its still get that problem. When I tried without SMAPI it works well

I'm just updating my SMAPI to 0.38.2, but it still.
there is some invalid mod dll when I launched it? is that metter?

That's caused by CJBs mod. I think uses that dll to handle saving his config file.
The error is fine :) It just means to say it tried to load that dll but found out it's not a mod dll.
