What is the macOS you are trying to install? How big is your storage and how much free space do you have?

Do you have access to a second Mac as well as a USB Thumb Drive which works across both. Or a USB-A to USB-C adapter cable to interconnect the two?

I had installed OS version 10.14.5. Installation was completed. Storage is 512GB around 400GB free Space .unable to access the Second Mac

Why did you reinstall the OS ? Does the touchbar turn on now ? What about keyboard backlight ?

I had the same issue but i didn’t reinstall OS, it happened itself. Apparently Touchbar died and it caused Critical Software update error. It was booting fine in safe mode though, except i did not have touch bar or keyboard backlight at all. I had the top case replaced under keyboard service program. Now everything is fine.

Well, thats the correct macOS, You’ll need visit an Apple Store to see if they can fix your system. I fear you have a bad flash chip.
