So I’ve come across a weird problem with my Unity(I was on 5.4, I upgraded to 5.5 when this problem came up). I’ve been working on a project for the past few weeks so I know my computer is capable of running Unity fine, I had no issues then. But out of no where now I can’t open Unity. The Unity logo screen that comes up before you login and select your project comes up, but it just gets stuck there. Opening the scene instead of the clicking on the desktop shortcut does not work either. I have no idea what to do and some help would be appreciated!

Having the same problem see if it’s your AntiVirus.
Checked that, still isn’t working
figured it out, you have to add an exemption for Unity.exe in the background processes section of Windows Defender.
How do you add an exemption because I am having he same problem?
I’m also having this issue. I tried adding the exception, but that didn’t work for me. Any else have any other possible solutions?
The editor is getting stuck trying to contact the update server (new version check maybe?). For whatever reason, the whole thing fails to open when this happens; maybe they don’t have a timeout or something.
On Windows, add this line to the file C:\Windows\System32\drivers\etc\hosts (if on Mac, do the same with /etc/hosts)
127.0.0.1 update.unity3d.com
Then make sure to kill any stuck instances of Unity, and relaunch. You might also have to log out and back in for it to take effect.
Apparently it’s some backend problem on Unity’s end - in other posts they say it’s been fixed, but here in the the office we’re still getting hit by it at random times. The hosts file fix is a bit heavy-handed but works every time.
Hey, thanks for getting back to me.
I added that line to the hosts file, but I’m still getting this issue.

Adding to Hosts and Adding the C:\Program Files\Unity folder as an exception to Defender worked for me on Windows 10 x64 with Unity 2017.3
And… it’s dead again.
Do you have a controller plugged in? If it’s the case unplug it and it should work. I had the same issue and I tried everything (antivirus, firewall, deleting files…) but this… worked like a charm and the editor showed up a few seconds after!

I’ve tried it without a controller plugged in and I still get this issue.
Thanks though.

Works for me.
Ok so its probably out of the screen so you have to shift + right click on the icon on the taskbar then press restore then shift right again and press move an your done
YOU ARE A GOD SENT,look everywhere,reinstalled windows,renistalled unity, struggle for 2 weeks just to find out its a controller
You are a godsend
For anyone having issues and you have a VR headset plugged in: apparently that’s a “controller”
I managed to fix this issue. I’m not exactly sure how I did it. But the last time I booted my computer I was greeted with about 5 Firewall prompts, including one from Unity.exe when I opened a scene. Low and behold it opened.
It’s definitively a firewall issue, if you can find a way to clear firewall settings, that might fix your issue.
Damn I finally got it, almost was going to use a different engine. I kept opening my project, and it would always show up on the taskbar- yet would be nowhere to be found on my screen. After the theatrics were over and me and the little shitter finished playing cat and mouse, I tried doing the ‘shift+right click editor on taskbar, restore, and move’ fiasco for what seemed like the 10th time and it finally worked. Turns out it was chilling the hell out extremely far away to the right of where my viewable screen is. I obviously wasn’t aware of that, but I figured that out once I started moving my mouse everywhere in desperation for something to appear.
I musta renewed that goddamn license 20 times before I finally got it.
