    Hello there,

    I've just upgraded my project to Unity 2020.1.2 from 2020.1.1 and one of my UXML files stopped working. I had recreated it but Unity was unable to save it, showing the same errors. I think it might be some issue with my USS.

    Could someone please take a look at my files and tell me whether I'm doing something wrong or is there a bug in new Unity version?

    Here's the error:
    Code (CSharp):
    1. Asset import failed, "Assets/_UI - Builder/ToolMenu/v1/Layouts (uxml)/ToolMenuPanel.uxml" > TypeLoadException: Could not resolve type with token 010003fa (from typeref, class/assembly UnityEngine.UIElements.TextDelegates, UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null)

    I don't see anything obviously wrong with your files. I might be the .svg background image, if the VectorGraphics package didn't compile in the new version of Unity, but otherwise, unsure.

    But can you clarify the Unity version numbers? You said:
    but one, that's a downgrade not an upgrade, and two, 2020.1.2 does not exist. :)

    Thanks for your answer.

    I meant this version.
    upload_2020-8-14_9-0-20.png
    I upgraded from 2020.1.1f1.
    I'll check if it will work without the vector graphics.

    EDIT
    Yup, that's the VectorGraphics. I removed the reference to the svg and then upgraded the project and it worked fine. After adding the reference to the svg again the uxml just won't save.

    So I guess I either stop using vector graphics until it's fixed or I stay on 2020.1.1f1.

    Thanks for the tip Damian.

    EDIT #2
    The Vector Graphics package seems to work fine though. All files are imported properly. It seems that the problem is in the UIT package after all.

    Looks like a regression. I'll try to investigate a bit and get back to you. In the meantime, I'd say yes, stay on 2020.1.1f1 if you can. You'll still be able to run latest UI Builder package versions.
