Dear,
There is currently an ongoing issue in 11.4.1.4 with deployments, which may occur when using "scanning credentials" to deploy a package. In that case, the wrong credential is passed, and the package is deployed by the system account.
As a workaround for now, you could try using "Currently logged on" instead. Depending on your package, this could indeed have an impact, but it could work.
We apologize for the inconvenience this is causing. We are prioritizing this to get it solved as soon as possible.
