Thank you, Misaki, for yourresponse! I appreciate your suggestion. I've checked Nate's answer in the provided thread, and it indeed sheds light on the looping issues related to physics constraints in Spine 4.2-beta. Following the recommendations in that thread, I was able to implement a workaround to stabilize the animation loop and mitigate the disruptions caused by physics constraints. Your assistance has been invaluable in resolving this issue.
Thanks again for directing me to the relevant information!
