I was getting the Ashbeard error. I too run the Comodo firewall, but all I had to do was set the SoT.exe to "Trusted" when it appeared in the blocked applications.
Also, in another posting about Discovering Services crashing, Ahbraxas helpfully pointed out the following.
"Guys, I've managed to come up with a simple fix. The comodo error is related to the update to Comodo to address the SPECTRE vulnerability found in Windows OS in January 18. It updates a DLL file in C:\Windows\System32 named 'Guard64.dll' What you need to do is back that file up, and then change the name of Guard64.dll to Guard64_old.dll. Now in about an hour, Comodo will b***h at you for needing an update, and update that DLL file again, but until you restart, you can play Sea of Theives."
I hope this helps.
