    Hey,

    Feel like I'm missing something here - just been using burst since yesterday. Created my first Job and it's using [BurstCompile]. Everything is fast WAHOO!

    But trying to open the burst inspector I get this error:

    Code (CSharp):
    1. Could not load Inspector: System.AggregateException: One or more errors occurred. ---> System.ArgumentException: An item with the same key has already been added. Key: Unity.Jobs.IJob

    We'll need a repro for this - maybe our method resolving has a bug that we're not aware of!

    Aha - seems to be an issue when the project is in Nintendo Switch dev environment.

    Just logging a bug now!

    Hey, which burst version are you on?
    If it's an old version could you try and update it to a never version, and see if the bug still occur?
    This can be done by:
    1. Opening Package Manager
    2. Clicking the plus icon top left corner
    3. Choose "Add package by name.."
    4. Insert:
    - name: com.unity.burst
    - version: 1.8.2

    And I don't have the "Add package by name" option, this is what I have:

    I'm on Unity 2019.4.40LTS

    I could definitely use a repro for this if possible?

    In regards to upgrading burst: It is possible to switch to a specific version by going into to package manifest, located at something like "root-of-your-project/Packages/manifest.json". Here you can write "1.8.2" next to "com.unity.burst" under dependencies. If "com.unity.burst" is not present, you can add it to the dependency list like:

    Code (CSharp):
    1. "dependencies": {
    2.     "com.unity.burst": "1.8.2",
    3.     // All other dependencies
    4. }
    "

    I can try to upgrade to 2020.3/1.8.2 and see if it works. But only to confirm you if the bug still there or not, we can't move to 2020/2021 due to runtime degradation with Nintendo Switch builds though.
