    Same scenerio as MIHKELT. Issue is still here, happening when calling LoadAssetAsync with addressables

    Got this error on 2019.1.11f today! It is NOT completely fixed most obviously because otherwise i would not have got this error. Can't upvote this issue because it is MARKED fix but it is not actually fixed. Perhaps there are improvements towards the fix but not completely fixed as it still happens in 2019.1.11f this day

    The issue is already fixed in 2018.3.8f1, which should arrive soon-ish.

    Saw that there were some SpriteRenderer and JobTempAlloc memory leak fix in 2018.3.4. I gave that version a try and still having the crash, just this time it doesn't spew out graphics errors in the console log anymore.

    Will this fix be coming to 2018 ?

    Roses are red,
    Violets are blue,
    My unity is crashing,
    and nothing to do.

    (This error maybe linked with some access violation error in builds that I have only with this kind of setup)

    Not fixed! Casting Shadows From Sprites still brings up this Error!
