    As the tittle explains, pressing "Overrides" on one of the prefab instances inside the scene causes a crash. This only happens on one particular GameObject. The rest of the prefabs and their instances do not cause this behaviour. If i create another instance of the same prefab, unity doesn't crash. If i delete the instance which is crashing unity and then create another instance of the same prefab, unity doesn't crash. If i update the prefab via opening it and changing something, the instance properly updates with the prefab, without crashing. If i strip the whole prefab, only leaving a Transform component and then clicking "Overrides" on the same instance, it still crashes.

    I was unable to troubleshooot why this one particular instance of a prefab is crashing, changing the prefab itself, various instantiations, none replicated the crash. This seems to be linked to some kind of manipulation of that particular instance of the prefab, though i do not know what i did to it to cause such behaviour.

    Not reporting it as a bug, since reporting unreplicable crashes is a waste of both mine and unity dev's time. Creating this thread so that in case someone runs into the same issue, they might know why exactly this is happening.

    Unity rev: 2019.1.0f2

    If it happens every time you try it with that GameObject in that project, we'd like a bug report with repro steps and the project attached, if possible, so we can look into it.

    What's the case number? We backport almost all Prefab-related bug-fixes.

    It seems your case is a marked as a duplicate of this one:
    https://issuetracker.unity3d.com/is...ow-in-instance-of-name-based-replaced-variant

    This bug should be fixed in

    2019.1.1f1
    2019.2.0a14
    2019.3.0a1

    If you are using an earlier version of one of these releases, please upgrade. If you're seeing this bug (or something like it), still in versions later than this, please file a new bug report, as the ones we have do not reproduce.
