macrium reflect mft corrupt error code 6

I got an external hard drive and created a clone of my C drive using Macrium Reflect. Before doing this I'd like to create a backup. So now I'm thinking the best solution would be to try perform a manual update or reformat my drive. Ever since then, these random symptoms have started and have increased up to the point where the computer is essentially useless. I thought it had frozen during the update, so I powered down manually and retried the update again, this time letting the black screen and cursor sit for a while until it eventually finished updating successfully.

Admittedly, I made a mistake during the update when my screen went completely black other than the cursor for over 5 minutes. These issues started happening after a recent update which I believe was the creators update. I've been running into issues with my computer such as random freezing for 5-30 seconds, extreme slow downs, start button not responding, applications crashing, Windows crashing with a blue screen, text missing in file explorer and other windows applications.
