I would suggest you to open an elevated command prompt and run the below mentioned commands:
a. Open an elevated Command Prompt from the Power User Tasks Menu. Just press the WINDOWS and X keys together and then click on Command Prompt (Admin). Click Yes to the User Account Control message that appears.
b. Type the below commands to run:
net stop wuauserv
rename c:\windows\SoftwareDistribution softwaredistribution.old
net start wuauserv
c. After running the above commands, check if they are able to install the updates for the Maps app and check the issue.
Hope this helps.
