  • Can you add some details about what you did before the problem occurred? – nohillside Feb 12 at 6:21
  • I am honestly lost... How did you even get into this situation??? There are two separate APFS containers on your startup disk! That should not happen! Fixing that will be no small feat. I am honestly baffled at how this happened unless you were messing around with diskutil apfs ... commands. EIther way, I'm afraid the only way to fix this may be imaging the BOOTCAMP partition somewhere (maybe an external drive, large enough to hold all 205 GB), removing disk0s4, then running Bootcamp Utility and restoring the partition it creates with your image. – Coder256 Feb 12 at 7:50
