[FIXED] How to uninstall Eclipse Feature Patch?

Issue

I am using feature patch to modify Eclipse Code. I install this patch and it works.

But now, I want to uninstall this patch, what should I do ?

I have tried to uninstall it in "Installation Detail" dialog, but this fails with the following error message:

Cannot complete the install because one or more required items could not be found.
Software currently installed: Eclipse RCP 4.23.0.v20220308-0722 (org.eclipse.rcp.feature.group 4.23.0.v20220308-0722)
Missing requirement: Eclipse RCP 4.23.0.v20220308-0722 (org.eclipse.rcp.feature.group 4.23.0.v20220308-0722) requires 'org.eclipse.equinox.p2.iu; org.eclipse.ui.workbench [3.125.0.v20220308-0722,3.125.0.v20220308-0722]

If anyone knows this, can give me some advice, thanks a lot!
