I have checked the attached file and it seems to be like a Spine editor side bug. Open your Spine project in the Spine editor and press the Clean Up
button with “knock2" selected and the second sequence key of "texiao/qiaomens1_1" will disappear. As a workaround, if you uncheck Animation clean up
on the export settings window, it should be played normally.
I have created an issue ticket for this bug:
https://github.com/EsotericSoftware/spine-editor/issues/725
We are sorry for the inconvenience, but please wait a little longer until we fix the problem.
We have fixed this issue in v4.1.18 and it has been released. Please update and check if the issue is solved!
