I have a simple unity game that I just started and it was running relaly smoothly but now it started being unplayable this afternoon, literally 15 fps and less but the game is super small itself so when I look at the profiler now the RenderLoop is taking suddenly 1 second per frame and I don't know how to go inside and see the call stack and potentially see what's going on there. I restarted Unity but no luck. Can anyone help?
