Thanks for the additional info! It seems as if you've just discovered a bug in the spine-unity json loading codepath, it's working with binary .skel.bytes export.
We have created an issue ticket here:
https://github.com/EsotericSoftware/spine-runtimes/issues/1902
We will let you know once we have a bugfix ready. Thanks for reporting!

On a related note, it is not possible to enforce a framerate/remove interpolation between frames of a spine animation in unity, right? We're going for a kind of traditional frame by frame type look
It is possible, we even have an example scene for it called Spine Examples/Other Examples/FixedTimestepUpdates. :nerd:
Remark: It seems as if all runtimes are affected, as this issue also occurs in SkeletonViewer. The issue ticket has been updated accordingly.
