    I even have a link.xml file:

    3.   <!-- <assembly fullname="Unity.Collections.Tests" preserve="all" /> -->

    11. </linker>
    Jobs 0.70
    Collections: 1.4.00
    Burst: 1.6.6

    This happens also when i try the latest versions.

    Does that identifier exist anymore? As in, can you find the docs that say it does?

    If not then perhaps some other library you are using must be updated.

    Interesting!

    Here's some options to consider:

    - something is wrong with packages (see below). Try that same set of packages in a fresh empty project (just copy the 
    Packages/manifest.json
    over and see if you get the same errors)

    If that doesn't fix it.

    - that burst compiler version has a bug
    - that version of unity collections (I'm not even sure what delivers that) has a bug
    - there's just a simple version requirement that the Package Mangler is failing to catch
    - there is something unaccounted for in your code that makes burst choke

    To fix package-y stuff:

    Extra unwanted packages in new projects (collab, testing, rider and other junk):

    https://forum.unity.com/threads/temp-unityengine-testrunner-dll-error.1133938/#post-7287748

    About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

    Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:
