Flowable Designer installation failing in Eclipse

I am not able to install Flowable Plugin in Eclipse 2023-09 (4.29.0).
I tried with both the URL https://www.flowable.org/designer/update/ and by downloading the zip file.

The error I am seeing is:
Cannot complete the install because one or more required items could not be found.
Software being installed: Flowable Eclipse BPMN 2.0 Designer 5.22.0 (org.flowable.designer.feature.feature.group 5.22.0)
