Hello!
Beforehands, thank you all for the support 
I’m currently developing a project that is already live for beta users. Most of them don’t have unity installed, since it’s more of an experience then a game, so the public generally don’t have the plugin.
What we are experiencing from feedbacks is that the player is crashing their browsers and sometimes the whole computer (mac and pc). It always crashes on startup. I’m not even sure if crashes after it fully loads my client.
Unfortunately I can’t reproduce and I don’t have a log file for that. In a lot of other computers and mac it works, but sometimes (frequently, even) the crash happens.
Since I can’t pinpoint a motive or something like that, I would like to ask you guys what are your experiences in this case? There’s any good practice in development to avoid something like this?
I’m using the latest version(4.5.0f6).
One thing that we did that lowered the number of crashes was to ask our users to reload the browser after they download it for the first time. But it didn’t solve for all of them.
Thanks
Can you ask your end users/beta testers to send to you the log files that are produced? Might help narrow down what’s happening.
