Dedicated Server Failed to Start

Same issue. ALL my servers are getting this, including the one I was playing last night, which I created because all my other servers weren't working. 

This is a new issue, as I could access all my servers ("saved games") maybe two weeks ago. Nothing in my antivirus, or permissions have changed, only the update.  

I have cleared all mods, though I was only using two server mods ("Epic Health bars", and "Wormhole colors"). On client side I've been using Craftpot, Combined Status, and Geometric Placement. Again I have disabled all of them. Some servers are using Wigfrid, some Wilson. I know the update was on Wigfrid, but same thing is happening to Wilson servers as main as well. 

Let me come back around here with some additional information: 

I have tried this on modded servers and unmodded servers. I have disabled and removed every mod. I have gone through every troubleshooting step from the links:

I can create a new server, and load that server. However, I did the same thing yesterday, and now can't access those. The level of frustration is quite high.

Actually... I'm not sure I have the same issue as Gerald here, as his issue seems to occur every year, and I've gone through all the steps to resolve. I will make a new bug, and update information.
