Try and boot your Mac from macOS recovery and reinstall the update from there
On a Mac with apple silicon:
- Press and hold the power button for about 10 seconds, until you see the startup options window, which includes a gear icon labeled Options. Select Options, then click Continue.
- If you never see the startup options window, release the power button, then repeat step 1.
On an intel Mac
- Press and hold the power button for about 10 seconds.
- Press and release the power button, then immediately press and hold Command (⌘)-R until you see an Apple logo or other image.
When you have booted from macOS recovery, first go to disk utility and perform disk first aid. After that reinstall macOS from recovery
