Dani has pointed you to the immediate fix (needs reboot with displays cleared because some display numbers have not been returned to pool properly).
The underlying bug is related to how the VNC plug-in for Jenkins is written. The Display numbers are not a resource that Jenkins knows how to wait on, so the build runs when it has an executor to run it, but will then fail. To resolve that would need work on Jenkins side, see https://plugins.jenkins.io/xvnc for the plug-in details. Realistically no one is likely to fix the xvnc plug-in (last had a release 3 years ago). The "modern" solution to this will be converting the platform CI instance to run on openshift so that the xvnc plug-in is dropped from use. That is what we are doing on CDT now and we haven't seen this particular error since. (I don't know how much effort that conversion is, and/or if it is scheduled to happen?)
