Upgraded from Mojave to Monterey - stuck in install mode

I upgraded my MacBook Pro (2019 / 13") yesterday. It has been stuck on the black progress bar screen for more than 18 hours now. I have tried to reboot in Safe Mode but it won't do it and continues to loop back to the install progress bar screen. Other than calling Apple Support, I'm not sure what I can do on my own. Thanks in advance!

MacBook Pro 13″, macOS 10.13

ReThink occurred here -


Below will Wipe the Drive of Everything ( ALL DATA ) including the Recovery Volume - there are not Do Overs - Period.


To perform this action will require booting from a Bootable Installer


This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Monterey would have to be done on a computer that Qualifies to run Monterey


Once that is done read on for preparing the Destination computer  >> Only works on Intel Based Apple Computers.


Extra Special Notation regarding the Touch ID equipped Apple Computer. About Startup Security Utility and Must Enable from Recovery Mode the ability to boot from External Drive Before Attempting 


1 - Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.


2- Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive. 


3 - It will present options >> Disk Utilities >> View >> View ALL attached Drives. 


4 - Choose the Upper Most Drive ( not the volumes indented and list below ).


5 - The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map. 


6 - Once that is done >> backup out of Disk Utilities and choose install macOS. 


7 - Follow the prompts and it may automatically reboot several time. 


8 - Upon a final reboot - Setup Assist will present with the newer version of macOS.

Would suggest have the machine Evaluate by Apple.


A couple of thing may have occurred IMHO


1 - Lack of Empty Space on the drive before the Monterey upGrade was applied. This is based upon the length of time to try and finish and not booting into Safe Mode


2 - Any possibility there is an After-Market Internal Drive installed on the machine. See several other persons when this situation - After-Market drive installed and Monterey would balk or not install at all.
