I am the creator of gimmicks etc. for VR Chat

When operated from the expression menu in SDK 3.9.0, the animation that changes the object's Transform does not work (such as changing Scale from 0 to 1).

If it's SDK 3.8.2, it works fine, but if you update to 3.9.0, it won't work.

These events occur even after uploading to VR Chat on Unity.

Changes such as material changes and shape key operations move.

Also, when each animation is played back in the Animation window in the editor, it is displayed without problems.

The data is managed using VRChat Creator Companion.

Also, when I had someone else test it, the animation worked without problems even in the SKD 3.9.0 environment.

Even when they both created new projects and installed packages had exactly the same configuration, I was the only one who encountered the bug, and the other person had no problems.

It seems that the probability of occurrence is rare even when searching the internet, but I'm in trouble because I don't know what kind of difference it occurs.
