Since the 1.5 update, the game doesn't launch at all. I play it on linux and i have this messages :

Running Stardew Valley

I have uninstalled the game, erased all the config files, but it changed nothing, I have the messages each time i try the game.

I've had an answer somewhere else and it is an old bug with Mono : https://stackoverflow.com/questions/49242075/mono-bug-magic-number-is-wrong-542

As they mention in the link above, adding this to the launch script should fix it :
export TERM=xterm

It works, the game launches again.
