Intermittent build failures

[darkxst]

I am testing out the reworked builder and seeing this intermittent failure, If I rebuild the failed workflow it usually works the second time.

INFO:__main__:Version is correct, picking /opt/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi

As of .slcs spec version 8, projects must not contain any warnings to generate.
To override this behaviour, opt in using --force.

I think I've run into this once but it's hard to tell why this is happening. Perhaps it's due to the daemonization of slc.
