GOG 'Control' Won't Run

As per the title, GOG’s version of ‘Control’ wont run. At first, it was stuck indefinitely on ‘launching’, but I managed to correct that by editing config.py. Now it moves from ‘launching’ to ‘stop’ and stays there for about 1 second before returning to ‘play’. My various logs are below, with the exception of the debug log which is, so far as I can tell, entirely empty.

lutris -d: Ubuntu Pastebin
I have been able to get Homeworld running, so I am fairly confident that something in Lutris is operating correctly, but do not know any more than that.
Any assistance is appreciated.

You are on Mint, Ubuntu or Pop - either way downloads and just install 0.5.16

Thank you very much! I had installed Lutris from the software manager instead of directly from the website and it was using an old version.
