"You don't currently have permission to access this folder"

[lalala]

I've created a clone of my Win10 home edition on a 2tb Sandisk USB SSD protected by bitlocker.   Windows works as expected.  The problem is when I'm logged in I cannot view the drive WINTOUSB: (D), which is providing the functionality normally seen in C: and contains all the windows and user files.   When I click on the drive in Explorer I see the the message "You don't currently have permission to access this folder".  Is there any way to access this folder when logged in?  I can access it from other computers, just not when logged in to the bootable version.
