The installation of Big Sur 11.5.1 goes back to 11.4 after reboot.
I am trying to upgrade a MacBook Pro Late 2013.
Is there any log I can check to figure out what the problem might be?
MacBook Pro 15″, macOS 11.4
Is there enough storage? Make sure about 50GB space is available.

Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.
Startup in Safe mode. https://support.apple.com/en-gb/HT201262 Choose the appropriate method.
To leave Safe Mode, choose “Restart” at the bottom.

Safe mode prevents your Mac from loading certain software when it starts up, including login items,
system extensions not required by macOS,
and fonts not installed by macOS. It also does a basic check of your startup disk,
similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and the kernel cache,
which will be created again automatically as needed.
If these steps don’t help, please contact Apple Support.
