Encountered with Unity 2017.1.1 on Mac OS 10.12 (also happens with a clean install of the latest patch release, p3).
I was working on a project that I’d had open for several days without exiting the editor. I needed to restart my computer so I quit Unity and rebooted my mac. Now, Unity hangs when opening any project, including a brand new one. This occurs after selecting the project from the launch window. No error message or crash window appears, it just silently hangs with “application not responding” in the dock. One time in about 15 attempts I was actually able to open a new, blank project, but the rest of the time it has failed, and I’m completely unable to work.
Any suggestions? I’ll just be sitting here banging my head against a wall, fondly remembering a time long ago when my tools were reliable.
More weirdness - opened up a different project in 5.6, and that worked. Did some more fooling around with 2017, came back to 5.6 and now it TOO won’t open that project anymore, nor can it open a new blank project. Something is seriously broken here.
After running into this with pretty much every Unity version I have installed, I figured it must be some kind of license problem. I deactivated my seat, deleted my license files, and went through activation again. This didn’t help.
Last ditch idea I had was to just pull my ethernet cord, just in case there was some analytics/license bullshit happening. Lo and behold, this works! So now I’m able to work again, and I now know that Unity is shitting the bed if it has access to the internet. I’d love a real solution, but at least I can do my job again for now.
This could be what we started seeing this afternoon. About 4 different developers all have Unity hanging after we select a project. After about 1 second the CPU use goes to 0% and stays that way. We tried a ton of things. It seems like a race condition. If we set CPU Affinity to just CPU 0 on project selector window, it will start loading the project, then we can set it back to all CPUs.
Edit:
This was on PC.
5.6.3p3, 2017.1.0f3, 2017.1.1f1, 2017.1.1p3.
Same problem here. On OSX startup of any project failed. We tried reinstalling different versions of Unity (2017.1., 2017.2.) but it didn’t change anything. Disconnecting from the Internet solved the problem.
Still flaky today. 2017.1.1p3 is hanging about 50% of the time I open a project!
5.6.3 also had an activation error when I opening it today, since I had deleted the license files yesterday. On second attempt it activated.
Thank god someone has a fix for this. Disconnecting from the internet got me past the freezing. I’m on 2017.1.1f1 and it just suddenly crashed and then wouldn’t open anything. I’ve spent the last hour trying various fixes before I found this thread.
I just tried this with 2017.1.0f3 and it worked for me. Tried the same project 6 times, 3 with your method launching the project successfully and 3 without doing it where project didn’t open.
I have the same issue, although it’s not consistent. If I create a fresh empty project, unity creates the project, then idles as a background thread, never opening the project. Some projects cannot be opened at all… unity goes into an idling background thread. I haven’t tried cutting the internet connection but even if that works, that’s no solution for me at all. I need that to work.
Once the project is openned, you can re-enable your Network and manually log in into Unity Services.
So you can have network and Unity
But its a pain in the butt having to disconnect your network everytime you want to open a project.
I am using a personal license, meaning I do not have a license key. Unity doesn’t allow me to use it offline. At least I don’t know how to manually activate anything without a license key, which as a personal user you don’t have.
