I would agree with Laurence that remodelling would help this part. When
I opened the part, sketch doctor reports sketch 23 (split3) & 28
(sweep3) have constraints to unresolved reference geometry. This tends
to add to the instability of the part, particularly since sweep 3 is
related to extrusion3, which is the diameter you suggested changing that
causes the crash.
An added 2¢ worth of opinion, I treat edge tapers like fillets and
chamfers, I place them all after the part is completed. When I edit a
part later, I move the EOP marker above the fillets, chamfers and
tapers, do the edit and then move it back down. This allows all my
sketches to be resolved to square edges and corners. Much easier
construction of the model.
