Unity won't open project

Question

Hey,

fast in short. I have 2017.1.1f1 personal version Unity. And what's up with Unity it can't open project? I've been working for like 8 hours and if I want to re-open to check something or etc. it won't open. Does this happening only to me or I'm missing something?

One thing found helped me is go to Task Manager and End Process Tree on Unity, but I shouldn't go there every time it does "this thing".

Any help is appreciated.

Answer 1

@iKazanova - Just experienced this issue and tried this solution on two different projects and it resolved both issues:

Under your project check the Temp folder for UnityLockFile. Delete it and try to open the project again. Click OK on the popup that you get on opening.

It looks like Temp should not exist if Unity was properly shut down so you may be able to remove the entire folder.

UPDATE:

Steps taken:

Prior to removing the lock file I had completely uninstalled (Uninstall, delete extra folders, purge registry) all versions of Unity. After reinstalling the issue still existed so I do NOT recommend doing this.
I tried deleting the lockfile on one project that was having issues and it resolved the issue. I tried deleting another lockfile and that project also opened. After the second project opened I tried the other projects and they all opened without having to deal with the lockfile. It may be the case that removing the correct lockfile will resolve the issue.

Other Options:

I have also seen a lot of posts that state opening from an open project resolves the issue. If you can find a project that opens, open it and then open the locked project.
If none of these options work then you can also send a report to Unity support. You have to include the affected project and it takes a while to send but may be worth it for a solution from Unity.

Having this issue after Unity crashed while importing an asset.

I can open other projects, but not this one. Unity process disappears without any report right after clicking to open my project. If I delete the temp folder or the UnityLockFile, Unity creates them, then crashes directly without any report.

Opening it after opening another project doesn't change anything.

If you have any controllers plugged in try to disconnect them. Worked for me

You totally saved me, my friend. Bought a new generic USB gamepad for testing and left it plugged in. It stops Unity from loading past the project selection and dies to the background.

I have been experiencing the exact same problem in the past few days, and I have to End Process the Unity.exe in the Task Manager every time! I thought it was because of my version: Unity 5.6.1f1 I'll keep watching this thread for answers!
