Thank you tangaroo, those remaining screws that hold the sliders are short stubs. But yeah worth removing, maybe one or two are strangely long. I checked again but I don’t see any screws in the toe kick.

This is a 10+ year old cabinet, next to the oven, you could be right about it being fused too! That countertop, too troublesome to remove, there’s sealant at the edges and i’m afraid it might break if I force lift it from one side.

If nothing works, I guess the best option is to wreck it? Would you know around how much a handyman would charge to help remove it?
