Unity Hub version reports as 0.0.0, refuses to sign in, crashes after a minute

Unity Hub has always worked perfectly for me, no exceptions. The last time I used it was yesterday, still working perfectly fine. However, today, it’s completely broken and unusable. It takes a few tries to open it, but when it finally does, it’s logged me out, and strangely the version number reports itself as 0.0.0:

The infuriating part is that none of the options here do anything at all. Period. I can click any of them as many times as I want, nothing will ever happen… until about a minute later, where the program will close with an extremely vague critical error:

I have NOT done any of the following since the program was last working, which was yesterday:

  • Turned the computer off
  • Ran any updates of any kind
  • Installed any drivers
  • Ran any programs other than a completely unrelated file compressor
  • Disconnected from the internet

meaning it completely broke on its own, no user intervention required. I tried the usual troubleshooting steps like reinstalling the program or deleting all the Hub’s registry keys and let them regenerate - they did regenerate, but the same issue happens. Since completely wiping all possible traces of the Hub from my computer and doing a fresh install doesn’t fix the issue, then the issue clearly isn’t on my end…

…especially since standalone editors refuse to launch, which also wasn’t the case yesterday! This screams “Unity server error” but no reports of this so far, and their status page only reports some game issues, nothing like this. I have seen some recent reports of people being redirected to a blank page while trying to sign in on the web browser, but I don’t have that issue, I can sign in just fine.

I really need to work with Unity, but Unity clearly doesn’t need to work with me!

Did you try deleting the download and package cache locations?
You may also want to dig into AppData and delete Hub or Unity related folders, or temporarily move them entirely.

Do you run any 3rd party antivirus? If so, try disabling or uninstalling that.

Yep, I removed all those as part of my troubleshooting process. No remnants were on my computer before reinstall, yet the issues persisted after install. I still suffer from the same issues.

In total, I’ve uninstalled Unity Hub, then deleted all Unity-related files from the following places:

  • Registry
  • AppData/Roaming
  • AppData/LocalLow
  • AppData/Local
  • Program Files
  • Program Files (x86)
  • Documents Folder
  • Temp Folder
  • ProgramData Folder

Then reinstalled. All issues persist. Unity is now permanently unusable for me unless this can be solved, and since I’ve 100% confirmed the issue is not on my side, there’s nothing more I can do.

Hello. I got the same issue in Unity hub. after a couple of restarting the Unity hub app and restarting my laptop, the issue remains. The issue is the application doesn’t open when I clicked on icon, but I checked that in task manager, it was opened in processes but app window doesn’t opened. When I clicked again on app icon, it opens the Unity hub window with label Unity Hub 0.0.0 and any of the buttons not works at all!
how can I solve this problem?!

Same for me, so I have the latest Hub version so it is not fixed still. Any resolution?

I forgot about this thread, sorry about that. I actually fixed it using the most basic troubleshooting step which I somehow overlooked - “Have you tried turning it off and back on again?”

Seriously, a PC restart fixed it. I’d removed all traces I could find, but a restart was needed for some reason, probably some cache somewhere.

i got the same issues and i figured out that it happens when a different user on my pc already has unity open.
to solve this i needed to close unity / unity hub on the other users profile and kill any remaining unity hub processes in the task manager
