Your objects overlap and are nearly coincident in some parts. This is causing trouble.
On your large part I would split the outside cylindrical surface with a plane at the maximum height of the smaller object.
The smaller object bottom surface is also coincident with the large object. Get rid of that.
With the smaller polysurfaces selected, use the _Trim command to delete what’s not needed on the large object.
Select the small object, run the _Split command and select the large object. Hide the large object and delete the surfaces which are not needed.
Finally join everything, run _Cap to close the planar opening and _MergeAllCoplanarFaces.
Step by step geometry is in the file.
