Overview
Hopefully this helps people whos game fails to even start; it worked for me after multiple re-installs & deleting of save datas failed.Good luck !
Getting To Where You Need To Be
To access your save data, do the following:
1. Press the windows button in the bottom left of your screen.
2. Type %localappdata% and press enter.
3. Scroll to and open forager.
Replacing The Broken File
After getting to your forager data, you will then want to grab the config file from the official Forager discord, pinned in the bug-reports channel; though I will be including a link to the file as well.

Then simply replace the old config file in your appdata forager folder & your game should start !
Good luck & apologies if this doesn’t help, but it worked for me !
