No error messages that I could find, from the terminal it looks like the game simply shuts down after starting:

Review the linked system information and steam-225540-log first, then reproduce launching Just Cause 3 under Proton while observing the terminal output. Done means the startup shutdown is explained and the issue records a verified resolution or the missing diagnostic evidence.
