Bug EditorOnly [GetComponentNullErrorWrapper] creating 15.9MB Garbage on every ScriptReload

    On every script reload, this strange entry appears in the profiler, creating a huge amount of garbage which slows down iteration times significantly.

    What is this? How can I get rid of it?
    Using Unity Version 2020.1.17f1

    Edit: We don't have any MissingComponents in our Scenes, I made a script to check and remove them, using 
    RemoveMonoBehavioursWithMissingScript()
    .

    (next line is also very strange - calling GC.Alloc 1.699.287 times on script reload? All in all Script Reloading takes 32 seconds, every single time - I want to fix this, somehow)

    Can it be temporarily removed? These extra calls has no use to us.

    Without further details, like e.g. some callstacks for these allocations I'm not sure I can give you any answer to this. I'm not even sure if I would share your assessment that the extra calls (I'm assuming you mean GC.Allocs caused by the GetComponentNullErrorWrapper calls that are marked as EditorOnly?) have no use for you, though I can appreciate that it might seem like that without you getting direct error logs in the console.
