I have this error with Windows Server 2012 R2. I get the error on any user who logs in to the server with admin access.

Server Manger cannot run because of an error in a user setting file. Click OK to restore default settings and continue, or Click Cancel to exit. The configuration section 'connectionStrings' has an unexpected declaration.

Did you install an old version of .Net or an application that might have? That's what it looks like at first glance.

Run sfc /scannow in elavated command prompt and check for errors.

You will get this log in  %windir%\logs\cbs\cbs.log path.
