SystemVersion.plist build version mismatch: 23F79 vs 21H1222

I keep getting this error while trying to install the post install root patches:

  • Starting Patch Process
  • Determining Required Patch set for Darwin 21 The following patches will be applied:
  • Graphics: Intel Ivy Bridge
  • Graphics: Nvidia Kepler
  • Verifying whether Root Patching possible
  • Patcher is capable of patching
  • Local PatcherSupportPkg resources available, mounting...
  • Mounted Universal-Binaries.dmg
  • Running sanity checks before patching
  • SystemVersion.plist build version mismatch: 23F79 vs 21H1222
  • Unmounting root volume
  • Please ensure that you do not have any updates pending

Previous build worked fine. Any idea?
