3ds max crashes when clicking on create new in spline operator (while you are not on the first frame) ..
Thanks, I'm aware of the issue and it will hopefully be fixed in the next build.
Peshang, in your tube file, if I shift+drag the tyspline icon to create a clone, it crashes for me every time (sometimes I need to open the tyflow interface or click on the base-level of the modifier).
Are you seeing the same issues? Asking because I started with your file.
I've been able to repro this here and should have a fix in the next build.
