I’ve been using the latest version of unity with no problems however since this morning whenever I try to launch unity to access the project selection menu nothing happens. Even if I try and launch a project directly from where it is saved nothing happens. I have tried re-installing unity however I am still unable to use it. Does anyone know how I can resolve the issue?
Make sure that the Unity.exe is not corrupted. Also, try ensuring that it isn’t blocked by your OS and that you are running it with elevated/administrative privileges. Maybe uninstall it and reinstall? That might fix it if none of the others do.
I have tired running it as an administrator and have re-installed it however the issue is still present
What OS are you on?
I’m using windows 10. Unity managed to launch earlier after taking quite a while however once I closed it up to see if the issue was fixed it stopped opening again. Also when I go to uninstall after trying to open unity the unistaller recognises that instances of unity are open despite them not showing on screen or on task manager.
If you’re auto-loading a project, and the project or scene has problems, things like this can happen. First thing to try when unity doesn’t launch is to delete the “library” folder in the project. Unity will rebuild it.
If that doesn’t work, then it maybe the scene is corrupted (there was an issue with TextMesh Pro causing this IIRC). In that case, you can try to rename the scene file, stop Unity from auto-loading it.
I’m not trying to load a project, I’m trying to load the project selection screen.
Unity may be trying to reload your last project. If this is the case, hold down the alt key while starting unity, and it will stop auto-loading the project.
If this is not the case, then look in the editor log, and post it here.
Holding alt didn’t seem to correct the issue so here is the editor log:

Well, that doesn’t give much information…
But someone else with the same problem here(Cant start unity 5.5B4 - Questions & Answers - Unity Discussions)
posted that this fixed it:
