    Hi everyone,

    Last week, I decided to return to Unity for my cursus and created a new project, but some minutes after creating this project, Unity did not open.
    I tried to open the project another time and Unity give me this error in attachment.

    I already tried to reinstall Unity and Unity Hub, delete Unity folder in AppData, Programs (x86)... Whether I create a project or open an existing one, it doesn't work.
    I do not even remember if I have already installed Unity 5.X.

    Does someone know how can I remove this issue ?

    Have a nice day,
