I had a print do the same again so I paused the print, sent M502, homed all axis and was then able to print the full Benchy test with no issues. I had disabled Stealthchop (trying different options) in firmware however it still used it so I disabled it manually. Here's my print in pronterface:
I'll be doing more testing tomorrow to see how it goes and if a bit of custom Gcode in my print can offset the issue until it is worked out.
It is strange that when the error occurs, the registry address changes. Can you send configuration files?
If you need it sending as a file, I'm not sure how to do that and just going out to work now. Thanks
I made a post in the main branch of Marlin & another user here has a similar issue.
What I have noticed is that the msteps go from 16 down to 8 along side a few other things changing. This doesn't always happen as soon as the print starts, one attempt got half way through the first layer before doubling movement, another it did it as soon as it had homed.

As requested by a reply in dydyamotya's post, here's the M122 before the print and after the issue and pictures of my TMC2209 and board.
