CCS/CC1310: CCS update for CC13xx/26xx support package broke debug

Tool/software: Code Composer Studio

I am getting the following error with an existing project (on a CC1310 LaunchPad) after doing a brief CCS update tonight which appeared to only affect CC13xx/26xx support packages-

[Start: Texas Instruments XDS110 USB Debug Probe]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

[Result]

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'Oct 6 2016'.
The library build time was '20:21:35'.
The library package version is '6.0.407.6'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '5' (0x00000005).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the XDS110 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for XDS110 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).

An error occurred while hard opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-242' (0xffffff0e).
The title is 'SC_ERR_ROUTER_ACCESS_SUBPATH'.

The explanation is:
A router subpath could not be accessed.
The board configuration file is probably incorrect.

This completely prevents me from doing CC1310 development work now.
