I have an anim project working on spine 3.6. I then upgraded the spine to version 3.8.93 and exported it in binary format. When importing the anim project into unity, it failed.

i use unity 2018.4.2 and spine-unity-3.8-2020-04-14.unitypackage.
Can i help you? Thanks very much.

It looks like the .skel file could not be parsed, which indicates that the file might not actually be in the 3.8 format. Could you double check? If it continues to fail, could you post the .skel file?

The file you exported is not a .skel file but a .json file. It loads fine in SkeletonViewer, which means it will also load file in Unity when loaded as a .json file. If you are updating an asset that's already been imported into the Unity project, then please make sure you export it as a .skel file as described here: Export - Spine User Guide: Binary

I use skeletonviewer 3.8.91 and i still can't open the anim file.
How do you open it? I used the latest version of skeletonviewer

Skeleton Viewer 3.8.91 opens the JSON file fine for me:

Your strange naming of scene1.skel.skel.json causes it to not find the images. We'll fix that, but you should export using reasonable names. Don't put .skel in the name if you are exporting JSON! That is just going to cause confusion.
