Project failed to open - This project is not valid

Hey, i wanted to try out unity and wanted to try and make my own game.
I downloaded UnityHub and wanted to learn it by opening the FPS Microgame, but unfortunaly everytime and try to open it I get an Error saying "Project failed to open - This project is not valid".
I have downloaded UnityHub on my SSD (D but somehow everytime i want to make a new project the following Message shows up (I will attach a screenshot of the Message)

I have already reinstalled Unity Hub, and I don't know what to do. I hope someone can help me

 

Delete that file(com.unity.template.fps-4.0.0.tgz) and then try to create the project again. You will have to download the template again. Maybe that can help.

In case you can't find the AppData folder, do this: (I am doing this on Win 7, so the text might change for other versions)
Open file explorer, click organize>folder and search options>view>show hidden files,folders and drives.(image below)

 

Where is the file, because it is not in my AppData Folder under Unity

 

still doesnt work for some reason..

 

i can't find the organise in file explorer (i'm using windows 10)

 

Make sure to go to unity hub not unity

 

make sure you have hidden and system files turned visible
