If I don't check "drop administrator rights"

How much security do I actually lose if I don't check drop rights?
Since most recent Win 10 1903 update and Chrome version 76.

I am getting pop up again asking to allow admin rights.

I am using Sandboxie beta to fix some permission issue that popped up

with the recent Win10 and Chrome updates. Previous that issue

was corrected by updating Chrome outside sandbox but now Chrome is 

updated both in and out of sandbox but in sandbox, but when I click on 

"about Google Chrome" it says can't access update server, where before

it was just trying to update and could not. I get a sandbox pop up asking to allow admin 

rights.

thanks
