Just install the lib32-libnm package. The one Steam is supplying is outdated with the new libgudev 238-1, by installing your own lib32-libnm your system will use that over Steams one and it should launch fine.

Same here. My current method is a self hosted website on my home network which showcases all available games, followed by a bash script download that will automatically generate the yml file for Lutris to fully install any of my 200+ games.

Whilst this is currently the best way I’ve found for my setup this app seems like the perfect thing to potentially swap to, if Linux was supported.
