I see here several directions
1.first of all, please validate that you use hp-automation-tools-plugin. if so , we did several improvements in the area,
Please try to use our last beta version [5.8.5-beta|https://repo.jenkins-ci.org/releases/org/jenkins-ci/plugins/hp-application-automation-tools-plugin/5.8.5-beta/hp-application-automation-tools-plugin-5.8.5-beta.hpi.]
2.if you don't use hp-automation-tools-plugin, then you've found a different problem and it most likely has a different root cause
3.inthe beginning of the thread I saw the following : Unable to delete 'C:\Jenkins\workspace\LabD_Build_Automation\Validate_LabD_VCSA\.git\FETCH_HEAD
Root problem of this is locks of git and its not related to hp-automation-tools-plugin plugin.
