Giant Atx MTB rear wheel quick release not opening Bike is a Giant Atx 27.5 2016

I have to replace the tube on the back wheel but the quick release lever is too tight and will not pull open, is there a trick to loosen it?
You can use a pipe that you wrap around the QR to have a bigger lever, but be careful not to apply to much force (because you will have a lot more)!
If the lever is stuck against the frame (so you cannot place your fingers around), try with a screwdriver first to pry it open(but put a cloth or something to prevent damage on the frame).

Perhaps the axle of the QR is rusty? -> WD40 then :)
