If the crank operator is broken or if the gears don’t turn easily or at all, then you will need to replace the crank operator. Take a picture of your crank operator and go with the picture to the replacement parts company, so you can find the perfect operator that is for your window.
To replace it you need to take the crank arm off the sash, and if the operator contains a split arm operator, you need to unhook it too. When you do that, slide or pry off the operator cover. And if it’s a removable cover, cut along the casement cover with your utility knife. Remove the trim screws along the top of the casement cover and pry the cover loose. You need to be very careful because the covers break easily. Then unscrew the crank operator and set the new operator in place. You need to align it with the screw holes and screw it to the jamb. But if the cover isn’t removable, the screws will be accessible on the exterior of the window.

Maybe you don’t need to replace the weatherstrip if it’s only loose in some places. If that’s the case, you just need to apply some polyurethane sealant where you see the loose ends.
But if you want to replace the whole weatherstrip, remove the sash and remove the weather strip and start placing the new weather strip into the groove. You want to start at a corner, and you will hear it clicks when it slides into the groove.
There is a possibility that your window is stuck shut, and it’s because the weather strip is sticking. Try to open it and then spray some silicone lubricant on a rag and wipe the weather stripping. But do not use oily lubricants, because they attract dust.
