Issue Can't launch Stardew Valley with mods

Thanks for the log. As you mentioned; no crash. It looks like SMAPI hadn't finished loading the game yet.
I'm not sure of your system requirements, but SDV Expanded is one of the heaviest modpacks around. So, it can cause startup delays due to the amount of things its loading into the game.

You can try verifying that's the case by waiting longer for it to start, or try removing SDV Expanded and see if it starts quicker.
