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?!
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
Repro’d in the latest Hub that released sometime this week. This seriously needs more QA… If a reboot would fix it, that means there’s not enough post-upgrade cleanup. I have trouble understanding how these breaking Hub updates get approved for millions of people to use.
Hello, I have been having this problem for almost 3 months.
I have repeatedly raised my problem with Unity support and tested different solutions. I even opened a forum here, but I could not solve the problem.
In the end, I reinstalled my Windows but the problem persists and no one is responding.
All it took for me was uninstalling, restarting the computer, and reinstalling, but it looks like I accidentally stumbled onto a much bigger issue here that others are getting a far worse version of. All I can recommend is looking for leftover registry entries too. I do believe Unity should have a separate uninstaller app that looks for these types of leftovers, like how Microsoft has an Office Uninstaller that does the same.
i am a new unity user and am having the same problems after restarting my computer 2 times, it is infuriating because this is not the only issue i am having, however, that is for a different thread.
Hello I am also having this issue as of right now, I tried resetting my pc, reinstalling it. I don’t know much about coding but I tried looking at the logs and I don’t really know what to look for, please help.
If anyone runs into this issue, you can clear the Unity Hub cache by locating and deleting the relevant cache folders. The primary cache folder is typically located at C:\Users\<username>\AppData\Local\Unity\cache. After that, restart your PC. That’s what worked for me.
