I have installed CU for SharePoint 2016, then I tried to run the SharePoint configuration wizard, but it's not really running. It appears to be running in Task Manager, but doesn't really work.
When I try to run it again, it's telling me that another copy of the SharePoint configuration wizard is already running.
I also try to open Central Admin, and it keeps loading but nothing appears, even if i keep it there for 1 hour. The strange behavior is that when I choose Central Administration option from the start menu in windows server 2016, it tries to open SP config wizard instead.
Any idea?
