Hello everyone,
We're working on a heap of bugfixes and potential crash fixes at the moment, but in the meantime, we'd like to share a potential workaround to some crashing.
(kudos to user "MAX Critical" for pointing this out in his review, thank you!)
On the main Steam window, click Steam > Settings > Broadcasting > Privacy Settings, Broadcasting Disabled
This seemed to completely eliminate the crashing the MAX Critical was experiencing. While it may not work for everyone, we recommend trying this fix out to see if it provides improved stability for you.
Post in the comments below if this worked for you!
