If you will export artboards in any fractional scale or by specifying height and width you will get correct output.
The best way to not get an extra pixel is keep your artboard coordinates in integers. You can achieve that by changing the reference point of artboard to top left and typing in the nearest integer or do Make Pixel Perfect(Object > Make Pixel Perfect). If size of your artboard is increased please manage that accordingly and export.
Thanks & Regards

I don't think this ever got fixed mine still does it in CC 23.0 Windows. Even if I align the it to be pixel perfect that doesn't always solve the problem when exporting the png.

This issue is probably happening because the artboard dimensions are not appropriate for raster export (i.e. are in decimals).
If you make x and y values as the whole numbers in the transform panel (not in decimal), then the extra pixels will not be added to the exported image.
That is the workaround, and it’s reported that it’s not always the case.
At the same time — Ai knows the size of artboards to be exported and yet it does not deliver the set sizes, which is not fair. The team is going to rethink the algorithm.
