Can confirm with exact mode, and in fast mode if I move cube, it starts working.

CC @Howard Trickey (howardt)

I can confirm as well. Found that the present scale of Cube in Z direction is -ve. Changing it to non negative value will make the modifier functional again (with Exact solver).

This is the same issue as discussed in T89391 (for the Exact mode). It seems that the bug report may be about the Fast mode, which is not guaranteed to work if edges are exactly coinciding with other faces or edges.

Thanks for clarification, will merge with T89391.
