There's a one-stepper.
W-Wing 15, pincers R4C9 and R5C5, strong link on 5 in column 3, sets R4C4 <>1 (and R4C5 as well, but that's fairly irrelevant). This STTE. |

I used Clement's 2 standard VH moves too but then I like to look for chains that solve it one step (especially ones with pincers on both ends).
(1=4)r6c2-r6c5=(4-7)r4c5=r2c5-(7=1)r2c3 => r5c3<>1. |
