Crop To Selection currently doesn't do anything when used through the quick menu. Instead, it seems to select the paint brush. I don't know.

Export PNG to Photos through the quick menu also don't seem to work, as it instead saves as a jpg.

I've been getting quite a lot of completely random crashes lately. I'm not really sure what information to provide to help monitor this particular thing.
It doesn't matter what size canvas I use.
It doesn't matter what brush I use, I think?
It doesn't matter what other aps I'm using.
Only things that come to mind currently are, possibly it could be related to Reflector 3's desktop screen mirroring, or somehow related to auto saving, ironically.

Expanded details:

If you try to cut an object while something is selected, *while* you are currently selecting a hidden layer, you will delete the contents of that layer instead. FUTHERMORE, if you try to undo, that layer is now forever broken and can never come back. after undoing, it always seems to have a sort of square chunk removed from what was originally supposed to be there.

Simplified Steps:
Draw [thing]
Duplicate the layer of [thing]
Hide duplicate layer
Select something in duplicated layer
Cut, with layer of duplicated thing hidden
Undo

I can't seem to reproduce this bug every time However, though I have encountered it three times now. Things seem to change based on when I have closed or open any/certain other canvases. Hard to say.
