Firebase app crashes when uploading profile image - swift

Question

When uploading the profile image to firebase the app crashes getting this error "malloc: Heap corruption detected, free list is damaged at 0x280165460
* Incorrect guard value: 10751132320
"app-name"(945,0x16f5df000) malloc: * set a breakpoint in malloc_error_break to debug
I pasted the code from my entire Controller with exception to the gradient function seeing as that is not necessary.
The purpose of this controller is simply to upload an image to Firebase. IMPORTANT: This crash doesn't happen all the time but when it does it is fatal to user experience. Furthermore, this crash does not happen on my setting page which gives the user an option to add three more images to their profile. Not once has that feature crashed on me.
Please I desperately need help!

I simply want the app to save the image and move on to the home tab controller
