Game chrashes on Linux when you Open save game file location because some linux distro lose the default file manager association so IF he is runding Ubuntu / Mint up to 20 the way to solve it, is to open a terminal and type the command below:
exo-preferred-applications
in the window navigate to utilitis and make sure to have the file manager be nautilus or something that works ok on you-re installed linux. Mine by default was left blank and the game chrashed due to it not finding a file manager association . The FAULT here it's not with the game ... but with the system .
