Upon disconnecting the Digispark from the USB and then re-initiating the upload process, the problem resolved itself.
Do a full uninstall of Arduino, then delete the Arduino folder and Arduino15 (back them up first if you have any sketches in there!!!!), as well as any arduino folders under Temp. Make sure the folders and all contents are really gone, reboot and try again if not. Then, do a clean install of the IDE.
