Error while installing Big Sur 11.7.2

When i try to install Big Sur 11.7.2 on my MacBook Pro (Retina, 15-inch, Mid 2014) which is running MacOs Big Sur V 11.4 , I am getting Error:

"An error occurred while downloading the selected updates. Please check your internet connection and try again."

I tried to install using safe mode but getting same error, I don't what to do time machine back and then update the system.

Please provide any solution is available.

I think you should try applying first aid on the disk using the system recovery and even resetting the Smc, cause it happened with me before and I’ve solved it using the following steps above and if it doesn’t work let me know again in reply.
