brew upgrade failed on macOS BigSur Error: Interrupted system call

We have more and more laptops having 'Error: Interrupted system call' while run  brew upgrade on macOS BigSur.

I switched off  Real Time Scanning > File on Sophos endpoint, then enduser could do brew upgrade successfully.

Since Real Time Scanning is quite important to us, we can't switch it off company wide.  

Could you work out a solution on this asap?

Below is part of error
