Close/wind up the window. Remove the inside door panel. Be careful with power window switch and door speaker wiring connectors. Disconnect them before pulling the door panel away. Remove any plastic covers that may be glued to the door. Have a look at the door handle from inside the door. You will have some idea as to how to remove it. Usually door handles are secured by screws from the inside. Locate and remove them. Remove linkages to the door handle then pull handle form outside.

Either the linkage connected to the handle has come off, or the piece on the handle inside has broken. You will need to remove the panel from the door and repair or replace the handle.

the inside of the handle break off remove it you will see it

If the drivers door on your 2004 Mazda 6 does not open from the inside or the outside then chances are the lock/latch assembly is jammed or you might need to replace it. In order to get the door open the inside door trim will most likely need to be at least partially removed to access the inner workings of the door. This is no easy task as the panel is designed to be removed with the door open. If care and patience are used this can generally be done without major damage to the inside door trim panel.

Since you can get the door open, half the battle is already won. Yes, open the door, pull the interior door panel and take a look around. Watch inside with a flashlight (towards the rear of the door) as you roll the window down to see if you can see what it's snagged on.

Sounds like the mechanism inside the door has come off, should be a rod and clip that holds it to the latch, it is also possible that the lever on the inside of the handle has broken since they are made of plastic it is possible.

the metal rod was not reattached when someone worked on your door. pull the door panel off (partially) and check the handle, follow the rod. If there isn't a rod going to your handle, it should be obvious what is wrong.
