Unity opens then closes?

Okay so i have been working extremely hard on an android game the past 2 months and i decided to take a two week break, so to my surprise 4 days ago i attempted to open unity and it refused to stay open, unity opens for 3 seconds and then immediately closes with no warning or error.

I have re-installed unity and restarted my computer with no effect.

I would like to know if this is a common issue and if a fix is available if not does anyone have suggestions? I have even attempted to install the free version and have had no luck

With regards, Tony (btw i tried to keep it as short and understandable as possible)

Do you know if it is trying to open a project on boot up. If it is it could be your project file is closing unity down. Hold down Shift Alt at the same time to see if it opens the project wizard.

I attempted what you have suggested with no success, i will attempt to open another project… i just hope my project is safe i put a large amount of time into it :frowning:

same error
