Repro: try to p&c union these two sweeps.

var001 = startSketchOn(XY)
  |> rectangle(center = [0, 0], width = 10, height = 10)
extrude001 = extrude(var001, length = 5)
sketch001 = startSketchOn(XZ)
profile001 = circle(sketch001, center = [7.06, 3.77], radius = 0.68)
extrude002 = extrude(profile001, length = 5)
