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 somet$$anonymous$$ng or etc. it won't open. Does t$$anonymous$$s happening only to me or I'm missing somet$$anonymous$$ng?

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

Any help is appreciated.

@iKazanova - Just experienced t$$anonymous$$s issue and tried t$$anonymous$$s 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 t$$anonymous$$s.
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 w$$anonymous$$le to send but may be worth it for a solution from Unity.

Having t$$anonymous$$s issue after Unity crashed w$$anonymous$$le importing an asset.

I can open other projects, but not t$$anonymous$$s 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 anyt$$anonymous$$ng.

I have the same problem as Xialya do. Sended crash report.

UPDATE

git clean -fxd helped me (t$$anonymous$$s command deletes all files that not present in git repo)

CAREFULL some editor settings can be lost

.gitignore

I don't normally have any knowledge to help people, but I just thought I'd add in that had similar issue as @eovento, I've been using unity with no problems at all for a year or so - last month I got SurfShark VPN and everyt$$anonymous$$ng stayed as normal. T$$anonymous$$s week however Unity just wouldn't load, no crash report, just failed to get past the unity splash screen - did the usual of uninstalling Unity, upgrading to Unity 2020, still no luck - disabled my VPN and bingo, Unity works again. Why the two don't get along I don't know, but thanks to @eovento for the info.
