    Maybe it's a local action oriented command issue. Mine records just 45% success to put figures in it.

    Jk, I exported my FBX again and it works now. Ignore my last comment.

    I had this exact problem in 2019.3.2f1. I updated to 2019.3.4f1 and it didn't fix anything. I still get those same errors in the console and the inspector is empty.

    I no longer get errors in 2019.4, but it also does not update animations!!
    Nothing will make it update animations other than deleting the meta file. I also found this problem in the latest 2018 LTS.

    Upgrading to the most recent release of 2019.3 worked perfectly for me. Thank you so much, y'all! I appreciate you all making and maintaining such a great games toolset.
