Unity hub error opening unity version 2019

Solution 1

This causes when you have multiple instances of unity installed on your system. Try to remove old version and then try to open your project, make sure you have completed removed your old version of unity.

If this does not work then make an empty project with same name and copy the old projects asset folder and replace it in a new project.

Solution 2

Project does not exist: /Users/user/Desktop

Looks like somehow Unity Hub is trying to open Desktop as a project. It looks like a bug.

You can try to press Add button and select project path carefully or to workaround this issue, the -projectPath command line argument could work, in theory it should bypass the Hub. Navigate to Unity's directory and launch it like this: ./Unity -projectPath <path_to_project>

You should send a bug report to Unity.

There are two ways to write error-free programs; only the third one works.

    After installing unity hub, I had Unity 2017 already installed. Then I downloaded Unity 2019 from the Unity Hub without any extra build support.

    Then I made a new project in unity 2019 from the hub. The project does not start. When I open it manually I get the following error message:

    Project does not exist: /Users/user/Desktop

    I tried restarting my laptop but the same problem occurs.

    What I notice when I make a new project from unity hub of unity 2019 that unity launches in the dock for one millisecond then it disappears. Note: I am using a mac

    What I think is that unity is opening then it closes instantly.

      then you need to change the folder in the hub when you made the new project, that folder obviously doesnt exist

      @BugFinder It is just crashing I already had other unity 2017 projects in that folder but also after creating a 2019 project in desktop it doesn't open.

      Are you sure it was the same folder or one that looked similar? such as instead of "/Users/user/Desktop" it was "/Users/yousoff/Desktop" ?

      oh no, it was "/Users/user/Desktop" this but the path is not the problem. OH and now the project is not being created at all. What is the problem? I can only create a 2017 project but not 2019's why?

    My problem was solved partially by deleting unity 2017 and reinstalling unity hub. Thanks.
