Hello! As of today (February 6, 2023), I am no longer able to open Anim State Graphs at all - when I double click on an Anim State Graph in the Assets folder, it does say ‘open editor’ on the bottom left, but nothing happens. This is consistent across different projects and both Chrome & Firefox from what I’ve tested thus far.
Here is an example project where it does not work: Test PlayCanvas Project - Anim State Graph Cannot Open
Please let me know if this is an issue in the engine or if I have set something up correctly.
