The release is published https://download.eclipse.org/birt/updates/release/4.21.0 Also the maven release is published:
I don't think there is anything actionable here.
Are you expecting it to invoke powershell rather than sh.exe or bash.exe? 
Given there has been no response to the followup question, I'll assume this issue is not an issue that can be addressed.
@fredg02 I tried to enable a larger agent but it croaks. Maybe it needs some more configuration enable Xvnc properly?
This issue is created: https://gitlab.eclipse.org/eclipsefdn/helpdesk/-/issues/6252

There will always be bugs that need fixing and, given that very few people (probably no one) test the ongoing builds, there will be always be regressions. So for me...
Producing releases is a significant amount of work so my thinking is to avoid doing yet more work. A milestone build solves the problem too and is no extra work...
