Closed 1.3.5 1.4.0

I'm receiving the following error at the end of the rust server loading:
Failed to check connectivity to the companion server: System.NullReferenceException:

Setting breakpad minidump AppID = 252490

To see if it was something that I may have configured incorrectly, I downloaded the most recent version of the Rust Server Tool and ran a fresh install.  The problem persisted.

I continued to try isolating the problem, and I found that when bypassing the tool and running start.bat directly, I receive the same error... however, if I manually edit the start.bat file  and remove the " ^" from the end of each line, then run the start.bat manually the error goes away.
