It's unfortunate that the control center no longer opens as expected when the icon is clicked, which can be inconvenient and less intuitive.
It's possible that the change was made for technical or design reasons, or to align with changes in the latest version of Parallels. However, I can understand how this change may be seen as a step backwards in terms of user experience.
If you haven't already done so, I suggest reaching out to the Parallels support team or posting on their community forums to express your feedback and ask if there are any workarounds or plans to address this issue in future updates. They may be able to provide more information and insight on the matter.
In the meantime, the current workaround of right-clicking on the Parallels icon and selecting the control center option may be the best option. It's not as convenient, but it still allows you to access the control center and manage your Parallels settings.
