Another day, and what looks like another bad image, or bad copy operation. This kind of thing might nor be your fault.
Let's first make sure you meet the minimum requirements for Windows 10:
- Any Intel Mac from 2012 or later.
- Your specific machine's latest version of macOS (Catalina, Monterey, Ventura, Sequoia, or Tahoe).
- Minimum 4-8 GB total built-in RAM.
- Minimum 64 GB free mass storage.
Next, let's rule out an insidious hardware issue (faulty RAM, worn SSD components, logic board, and so on).Restart your computer holding the "D" key to launch Apple Diagnostics. Write down the code you get at the end. If it's anything other than "ADP000", look up the code and take notes for a shop visit. If you get "ADP000", that is an "all clear" code. Move to the next step.
You mention you're on Sequoia. Make sure you have all updates available (version 15.7.2). Go to System Settings to check it out. This may also upgrade the firmware of your SSD and other components. None but the "professional" units can move to Tahoe, and even then, it may not be mature enough right now to do an upgrade. Also, if you run anything at the system level (anti-virus, hardware management, system tweaking, etc.(, update that stuff as well. You may want to turn off these components for the time being.
One last thing before you try the Boot Camp do-over: you'll need a proper ISO image of Windows 10 version 22h2 (64-bit). Get this from Microsoft, or pull it using a Media Creation Tool on a separate PC and copy the ISO to your Mac.
Once you have all the pieces ready, re-run Boot Camp Assistant. If you get stuck again, take note of the error messages you get and follow up here. There's a good chance that someone else may know something I have yet to run across.
