Fixed in craft-providers 1.20.1 by auto-cleaning base instances with incomplete setup, with immediate cleanup when the creating process is inactive.
Resolution: closed resolved
Reason: The parallel-build race was addressed in the 1.20.1 release. Its changelog states that an existing base instance not set up is auto-cleaned, immediately when its creating process is inactive.
