Hi,
version 4.1.1 slices this model differently when comparing to previous versions: https://www.thingiverse.com/download:3333750
vase mode, layer height 0.15mm, 3 solid bottom layers, no layers at the top
see attachment. why is it so? The model looks fine and many people printed it without issues on other slicers. Confirmed Mac and Windows versions of 4.1.1 does it like this. Looks like a bug to me
