my game is completely bugged

[wheat estuary]

When I enter, no more characters appear.
and when I put play in front it joins me to the library map
and as my progress is restarted you caves that I play again

Please, I want a solution, since I bought it when it was coming out and when I played it from another account and played again on my account, everything got buggy

Have you reverified the game files on steam?

I tried many ways, but none worked for me
