yugutou Thank you for reporting the problem with 4.2.44-beta. It seems that the curves are only incorrect under certain conditions, so could you please email us the Spine project that can reproduce the problem?: contact@esotericsoftware.com
You don't need to send us the image files, just the project file. Also, as long as we can confirm the problem, you can remove bones, slots, or animations that are not related to the problem.

Thanks for sending the project file! We have fixed this in 4.2.46-beta, available now.
