Can't fillet simple block with threaded hole

[kenehlert1959]

I created a simple 40x20x20 block, added a M6 threaded hole centered on the block and grouped the two together. When I try to add 1mm fillet, it says "The grouped body could not be repaired into valid geometry". Bug report is attached.

@kenehlert1959 the block with the threaded hole can be filleted in 1.114.0. The cut was valid, but merging its faces afterwards broke it when the hole's chamfer was as long as its pitch, which a new threaded hole has. Your bug report made it quick to find.
