Upgrading wp8 to wp8.1 silverlight, debugger cannot be launched

I have now had an error with VS2013 and WP8.1 silverlight for a couple of days.

I get a couple of different errors, ..Ensure unlocked screen.., AgHost.exe could not be launched, port is in use by another program and ensure the device is unlocked.

These errors came suddenly after I retarged the solution. I have no compiling errors. Solution Attempts

1. Restart PC
2. Restart program
3. unregister and reregister the phone
4. reinstall Update 3
5. reinstall VS2013
6. Windows Phone 8 Application crash once its launched AgHost.exe' has exited with code -532265403
7. Install VS2015 with no luck.
8. reinstall VS2013 Update 4

Nothing worked. The error is also the same for emulator as well as different devices. I can however get the release mode installed. Break points can be used when using release mode, but I have to Clean, Rebuild and then deploy for every time I want to deploy the application. Further the deploy time has gone up exponentially. Before upgrading I used a maximum of 10 seconds. Now it is above a minute in wait time. :/

Anyone has a solution for this ?

Extra

If I run the solution before upgrade on device or Emulator It spins up with debugger. If then go to the updated WP81, I get a popup with info Something is taking longer then normal and then it crashes with ..Ensure unlocked screen.. :/

Could it be an issue with the differen SDKS? During a repair of all the SDKs, I found an issue with the event log, which I cleared based on The Event Log File is full

Still no success.

Extra

I cannot spin up the emulator from VS2013, when using the WP8.1 solution, but the wp8.0 solution in the same VS works :S

I found an error in a log file, from:

Anybody knows what to do with this? The error is coming when I repair Windows Phone SDK 8.0

There was a post-VS2013 update for the Windows Phone 8.1 SDK, some odds that you don't have it installed since you did not need it before. The download location is here.

Getting error messages like "port is in use" when there's no obvious reason why it should be in use and seeing excessive download times is also a very strong selector for your installed anti-malware product getting in the way. No specific advice on how to configure it when we don't know what it might be. You definitely first want to try to temporarily disable it so you can identify it as the source of the problem.
