How do the first and second commands look? Are they the same, or do they have different input targets and templates? This would be super helpful for identifying the issue.

Regardless of whether the same command or different commands are executed, a specific file becomes locked, causing subsequent instances of Nuclei to fail and resulting in this bug.

Anyway, we still need the exact commands you used so we can reproduce it and dig deeper from the info you shared.
