    I'm not too familiar with Vuforia, but the first error looks like a native DLL is missing. Do you know if a native library should be present? If so, it is in the correct location near the player build?

    If you are building for arm64, then the native library will need to be built for arm64 as well.

    I don't know enough about Vuforia to say, sorry. I suspect that they have an arm64 version available though.

    @glutvort , I recommend that you try Unity 2018.4.6 (LTS) instead of Unity 2019.X.

    Since Unity 2019 has a considerable amount of new changes, using Unity 2018.4.6 is safer.

    Regarding your errors, after you migrated your project to the new Unity and Vuforia versions, did you update the Vuforia library assets within your project? I recommend removing all old Vuforia library files and re-importing the new library into the project.

    @glutvort, from your error logs the issue seems related to Image Targets, if so, try to see how you are loading them. Are you loading them dynamically or via adding them manually into the Scene?

    If you read the error closely, Vuforia is throwing an exception as it is trying to traverse the database of Image Targets but the collection is changed while traversing it. Are you adding/removing Targets while Vuforia is initializing/updating?

    Unfortunately I don't know how else to help you. This issue is somehow related to your project. Try to contact Vuforia support.
