It may be a wiring problem in the model. Check your model wiring, especially the junctions between surfaces. Avoid triangular faces and 5-sided faces.

If it still doesn’t work, open BEVEL OPTIONS, select the default state, and select the appropriate WIDTH parameters (depending on the size of your model).

When FAILDE occurs, it is mostly caused by problems in your model itself. Check your model more, including whether the surfaces are connected, whether there are redundant points, etc. If it still doesn’t work, you can send it to me. Let me check it out for you.
