Hi,
I recently upgraded our project to 2017.1.0f3 and i got this error twice today :

I can’t tell exactly what is causing this, but i know for sure that in the 2 times where it happened, it happened after not using the editor for a while, in both cases i was browsing using Chrome and unity was running on the background (the game itself was running too, [play button is pressed] ) and when i went back to unity again, stopped the play session, then press play again, that error happened.
Any idea what’s going on ?
Thanks
