Unity 2018.4.35f1 Steam Overlay Crash

Hey there,

With the recent Steam update we have found one of our games that is built on Unity 2018.4 LTS has begun crashing after the resolution selection. We suspect it is likely the Steam overlay, and see this as the crashing stack trace:

Is anyone else running into this, and is there any suggested fix? We do not see this consistently for all Mac users. This particular crash log came from Mac OS X 10.14.6 (18G8022).

The call to
20 gameoverlayrenderer.dylib 0x0000000109a87d12 0x109a6d000 + 109842 is what has us suspecting Steam. Another game title using Unity 5.4.x is unaffected by this new Steam overlay (confirmed by people who plays both games).

 

We've gotten a few players to try enabling/disabling the Steam overlay and it has no effect, the game continues to crash. We haven't modified this build recently, and it only started crashing after the recent Steam update, so we're not too sure where to go with this at the moment.

If the game is launched directly (instead of via Steam) then it loads fine without crashing.

 

Steam just released a new version of their app and it appears to now be fixed.
