Front and inside camera quit working.

Both front facing cameras, the front when it's closed and inside when it's opened, stopped working at the same time. When I try to switch to a selfie camera I get an error message that says it's a hardware or software problem and returns to the back camera. I've tried restarting, clearing the cache, and updated all my software. When I open Zoom or other software which requires the front camera I just get a blank screen. My research has said it might be a flex cable but I can't find which cable, where I could purchase it or even if it's possible. Any help would be greatly appreciated and if you have the parts, tools, and instructions, please let me know. Thanks for your time and attention. Sincerely Randall Scoggins
