As I'm on Windows 10 Fall Creator Update, I'm quite surprised to see this message on the console:
[NoCrows] You've downloaded the Windows version of No Crows. If your game crashes at the end of the day, you need to download the right version for your computer instead!
Looks like there is a bug with the way it handles the check.

• Steam version of Stardew Valley
• SMAPI 2.5.5
• No Crows 1.1.0 on Nexus.

Hi @Inny78. No Crows always logs that message, it doesn't actually check your platform. That has little to do with SMAPI, though. Feel free to post suggestions on that mod's Nexus page instead. :)
