Flashing between prohibition sign and Apple symbol on boot.

Hi everyone,

I was recently using my MacBook Pro when it suddenly froze, did a quick restart (Holding the Power key). When I was greeted with the prohibitory sign. After doing a bit of research and doing all sorts of things pram reset, verifying disk in recovery mode etc. I decided to restore the disk as I had just done a time machine back up. After restoring I usually get as far as installing 10.15, when at some point during the initial setup i.e setting up new user, or the second time I did it when I booted into the desktop for the first time, the computer freezes again and then after restarting I have the prohibitory symbol again but it flashes between the Apple symbol.

I’m a bit stumped on what to do, so any advice would be much appreciated.
