    These errors keep popping up every frame, as does a MouseEvent error. But I'm not even using mouse events... "Screen position out of view of frustum" each time I hover over the Game View on Play Mode.

    It just started doing this this afternoon.

    In a Development Build, this also happens: Both errors flood the console thingy. It's a tad irritating searching through that for actual errors in MY scripting.

    Any idea what could cause this? And can I send anything over to help?

    Sadly I didn't. This has been going on for a few different Unity builds now.

    Struggling with it, too

    "
    Assertion failed on expression:'std::abs(det) >FLT_MIN'
    UnityEngine.GUIUtility:processEvent(int, intptr, bool&)
    "

    Even don't know what happened...

    In my case, appeared when I put a canvas just in front of the near clipping plane (but inside the fustrum)

    In my case:

    I had my pause script set timeScale to 0
    And when I reload the scene it didn't automatically reset to default, so that it confused trails, lerp, smoothdamp, etc. functions
    So I had to manually set it to default in Start() or right before reloading

    Thats strange. The only place I can see an assert like that is in the shadow culling code.
    If you have a project producing this error please file a bug report so we can look into it. Asserts are things that should never happen.

    I ran into this bug today too. Thanks to the above replies I was able to track it down. I had a SmoothDamp controlling my cameras orthographic size every frame. If I changed the orthographic size value while Time.timeScale was zero the error messages appeared. (21 errors in my case). The solution was to simply put a check to ensure the smoothdamp code didn't run unless timeScale was non-zero.

    For future reference I was seeing this assertion when setting a camera's aspect to zero and calling Render() on it. Fixing the aspect value made it go away.

    Disappeared when I turned off the Render Shadow option in the VR camera.

    Same issue in 2022.2.14. No shadow from my directional light, ever, but other lights work ok. The only shadow i get is a thin strip in the global Y plane. The assert is intermittent.
