Bug/Issue Game Won't Launch, no error log

Hiya - as the title says. I've played 500+ hours of Stardew prior to this issue. When I click Play in steam, I get a loading cursor for a couple seconds and the game says it's "Running" and then doesn't open. No process opens, and I get no error log or error message. I've tried pretty much every fix I've been able to find (the headphones fix, deleting the startup preferences file, verifying files, removing smapi, reinstalling, using Big Picture mode on Steam, etc).

I played it just the other day, but since then I've unplugged my computer and moved everything. I don't know if something minute has changed with my machine since then that could be causing this? I'm getting Stardew withdrawals!

Any help would be appreciated, thanks a bunch

 

We'll need more info. Can you try these steps?

1. Install SMAPI.
2. Launch the game through SMAPI.
3. Upload your SMAPI log to log.smapi.io (see instructions on that page).
   
4. Share the log link here.

(You can remove SMAPI later, we're just using it to see what the problem is.)
