I have two Cubases 10 on my computer

I have recently switched to a new laptop (MacBook Pro 2020) and after reinstalling Cubase I released that I have 2 cubases 10, one on the application folder and another one is on my desktop. This is not just an icon on my desktop, when I search for cubase in Finder I see 4 portions- cubase9, cubase 9.5, cubase 10 ( and cubase 10 ( cubase is also casing me a lot of problems recently, like closing from nowhere and not showing the last saved projects.
My question is whether I can delete an extra cubase 10, as well as 9 and 9.5 and if so, which one should I be keeping? I usually work with cubase 10 (, bit its being problematic as a mentioned before
