Canon 5D Mark II fires shutter but records no images and shows black/striped display

My Canon 5D Mark II was working normally with Magic Lantern installed for both photo and video, but one day it stopped capturing images. The shutter still releases, but no photos are saved. The rear display shows a black screen with horizontal and vertical lines, and Live View is black and freezes.
I have already tried removing Magic Lantern, reinstalling Canon firmware 2.1.2 twice, formatting the memory card, removing and reinstalling both the main battery and the small date/time battery, and testing without a lens. Nothing appears physically broken in the mirror box.
Could this still be caused by Magic Lantern, or does it sound more like a hardware failure?

It sounds like some kind of issue with the digic chip itself. Since things were working after the install of ML for a while, I doubt ML was the source of the problem.
I don't know if it is the same for the 5D Mark ii, but I know that on my 5D Mark iii, the shutter actuation and image capture is distinct from the menu system itself as I had an issue with moisture causing my menu systems to not work for a while but I was still able to capture images.
It sounds like you are having the opposite problem, the shutter actuates fine and the circuitry responsible for driving the menu system is fine, but the actual hardware responsible for driving the sensor and image capture appears to be malfunctioning.
I doubt there is much you can do other than sending it in for repair as you've already done all the user serviceable stuff I can think of. Most likely either the sensor itself or the digic chip that processes the output of the sensor will need to be replaced.

This sounds much more like a hardware fault than a Magic Lantern problem. Since the camera worked normally for a while after installing Magic Lantern, and removing ML plus reinstalling Canon firmware did not fix it, the likely issue is in the image-capture path: sensor, image-processing electronics, or related circuitry.
The fact that the shutter still actuates but no files are saved, while Live View is black and the display shows lines, points to a failure in the hardware responsible for reading or processing sensor data rather than a simple settings or card problem.
At that point, there is usually little you can do at home beyond the resets and firmware reinstall steps you already tried. The practical next step is professional service/repair. If repair cost is high, compare it against the value of replacing the body.
