Windows Standalone crashing in UI code

Our recently released game keeps crashing on some machines every few minutes.
The game crashes with an "access violation’. Seems like some engine code problem, trying to access memory it shouldn’t.

I sent them a development build with symbol files, and this is the log we got:

Other logs are similar. It seems to be hapenning in the UI Batching.
I opened a bug in Unity but so far after a week there has been no response.
Case number: 788681

Can anyone assist?

Its with QA at the moment. Are you able to share the project or a cut down version which exhibits the problem?

Thanks!

Would a dev build with pdb and symbols be good, or do you need the actual project?

Yeah a dev build can work. Which version is it built with? Ill dm you with vpn details so you can upload it.

The game was released with 5.3.4, and then I tried 5.3.4p2 since I saw it solved several crash issues.
As soon as 5.3.4p3 was released I tried it as well, but it kept happening.

Hi guys, did you ever find a solution to this? (Sorry, I see this is an old post) We’re having the exact same problem in Unity 5.3.6f1 and it’s preventing a handful of players from being able to play our game.

Either it stopped happening, or players just stopped complaining about it… But in any case we were not able to identify what caused it, so there was no intentional fix.

Thanks Tomer. I’ll keep digging.
