I'm unsure why the bot build under version 1.73.0 failed. The logs available to me are not enlightening either. I'd appreciate it if someone would take a look at this.

projects like boost take a lot of resource to build... which means sometimes things break

You'll need to retrigger CI, close the pr wait 10s and then re-open it 🔁
