Error while creating flowable project on Eclipse

Hello, I have been trying to work with the flowable plug-in Eclipse. After several tries I have not been able to resolve the errors.
NOTE - I am working on Eclipse version 2023-09 and flowable version 5.22.0

When creating a flowable project (within the flowable perspective), I get the following error-
Unable to find persective org.activiti.designer.eclipse.perspective.FlowablePerspective in BasicNewProjectResourceWizard.updatePerspective

When creating a flowable diagram (within a flowable project, I get the following error-
java.lang.NoSuchMethodError: 'void org.eclipse.draw2d.FigureCanvas.setScrollbarsMode(int)

Any help regarding this is appreciated!
Thanks
