macbook Pro 2015 will not boot

Hi, I am lloking for some help with a booting issue with a 2015 MBP following the update to OS monterey. Initially it would get to the lock screen and then get stuck on the log in so I followed the following steps:

Reset SMC/PRAM

Power cycled

Checked drive is disk utility - no issues

Booted in safe mode and removed all start up items

Reinstalled IOS monterey

All of this failed to solve the problem. I decided to completely wipe the laptop and and reinstall the os, on completion of this it logged in ok, however when I shut the laptop down it then failed to boot and wouldnt get to the lock screen. It will still boot in safe mode, but when i tried to reinstall the OS again after running out of ideas it got stuck again, I left it updating over night and nothing happened!

Does anyone have any ideas what the next step should be? is this likely to be a hardward fault?

If the laptop can boot into Safe Mode, but is unable to boot normally, then it usually indicates a problem with some third party software that is installed since Safe Mode prevents third party software from launching automatically during boot & login. Usual culprits are anti-virus apps, cleaning/optimizer apps, and third party security software...none of which are needed on a Mac. If you are using any of these types of apps, then uninstall them by following the developer's instructions. If you still have issues afterwards, then run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
