Are you running the commands with an administrator account?
Access denied means you don't have enough privileges to create that folder.
It can't find
lnd.exe because it is not in the current directory. Navigate to the directory where the .exe is placed (seems to be
C:\Users\Ezra\), then try it again.
Finally, I moved my Lnd folder back into %localappdata% and tried to launch lnd.exe through PowerShell (non-administrator) using all the same commands/flags as before, resulting in this error message:

You seem to not have enough privileges (which is quite weird). Are you on a 'guest' account? Or an administrator account?
