Good evening all, I just downloaded Unity today and had started going through the tutorial: Create Your First Unity Project when I reached step 5: Create Your First Project. All was going well, I had selected FPS of the 3 choices and I was moving right along through the modules, changing the floor color, adding another enemy, taking a picture for the thumbnail to your game, and then I reached a point in the module where you have to upload a thumbnail. Long story short I was having trouble finding my thumbnail, which led to repeated module attempts, frustratingly moving file locations around facepalms, which led to an attempt to start fresh by deleting the first mini game project entirely from unity hub and re-installing unity and unity hub multiple times. As you can imagine, this caused a problem since I could no longer reach the prompt asking which of the 3 tutorial mini games I would like to try, or my project as I had deleted it. Instead I was brought right into the hub, without the mini game prompt. So now I’m stuck and not sure how to restart step 5. Please help?
(Edit: I am unable to start any other projects either, an error for the editor states that the application pathway does not exist)
Please show a screenshot of your issue
Just an update, I downloaded an earlier version of unity that is compatible with the tutorials: 1. Play & Edit Mode, 2. Game Objects and Components, 3.Tweaking Components - Values vs. Zombies, 4. Prefab Power - Ramping up, which incidentally I was also struggling with accessing yesterday because, as I now understand after referring to the forums, I was using Unity 2019.2.10f1 instead of one of the compatible versions conveniently listed under each unity project/tutorial. So I downloaded version 2018.4.0f1 and have had great success with all of my issues! I was able to now download the tutorials mentioned above and was able to download the FPS mini game from Unity Learn that I had started working on yesterday (“FPS Microgame”) before all the issues began. It even had all of my progress from yesterday saved somehow even though I was using a different version of Unity. Here I was under the impression that the only way to access the three mini game/tutorials was when one creates a new account, as though it was a one-time sort of deal, but fortunately it is right there in Unity Learn which… makes a lot of sense. It was unfathomable to me at the time however after having failed so hard on my first day with my first game engine ever. To conclude and I just tested this awhile ago, if I try to download anything or attempt to start any new projects while using Unity 2019.2.10f1 then I still have the same issues I described yesterday, for now it seems having downloaded version 2018.4.0f1 has been enough to allow me to continue my unity education. 
Also, JeffDUnity thank you for responding, if I run into any issues related to what I was experiencing I will try and post some helpful screenshots.
