"Compilation error: Error: 2 UNKNOWN: exit status 1" error

I recently installed the beta with these:

Windows 10 64-bit
Latest git version (2.30.1) 64-bit

Attempted to run example code 'blink' and ran into this:

c:/users/anton/appdata/local/arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/../lib/gcc/avr/7.3.0/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference to `main'
collect2.exe: error: ld returned 1 exit status
Compilation error: Error: 2 UNKNOWN: exit status 1

Is this due to the fact I have not resolved the issue that popped up before that led to this link? This notification popped up when I first ran the IDE but I don't see it anymore... Is this unrelated?
