Convert Handle(Adaptor2d_HCurve2d) to Handle(BRepAdaptor_HCurve2d) cash in occt 7.4.0

Hello everyone, when I use the fillet corner function of occt 7.4.0, the program crashes.

I tried to debug the source code and found that the problem is here: Convert Handle (Adaptor2d_HCurve2d) to Handle (BRepAdaptor_HCurve2d) cash in occt 7.4.0.

The debugging results are shown in Figure 1 2 3.

Thank you all.
