I installed several desktops but only wan`t Cinnamon how can i delete the other`s ?

I installed Debian 10.4 and several desktops by mistake but only want Cinnamon so how can i delete the other`s but keep cinnamon and related packages ? Right now it seems a mix of packages which is causing some problems as some don`t work like they should. If possible i don`t want to reinstall the whole Debian OS, any solutions ? The current desktop is Cinnamon but it does not function like cinnamon and different packages are there but should not be like Mate - GENOM - Xfce etc. everything except cinnamon only packages.
