Creating a new project gets stuck on "Initial Asset Database Refresh"

Attempting to create a new project from a template gets stuck forever on this step. Uninstalled and reinstalled all of Hub and the Editor and its modules, and restarted PC between those steps.

Unity Hub 3.10.0
Editor 6000.0.32f1
OS: Windows 11 Pro 23H2 22631.4602

Editor.log at the point where it gets stuck:

(this then repeats forever while I keep the Open Project window open)

Sounds like a process couldn’t start. Are you running any 3rd party antivirus?

Hello,

You’re facing seems to be related to connectivity with the IL Post Processor, and it’s likely caused by a configuration or permission issue, or possibly a bug with Unity Hub/Editor 6000.0.32f1. Try the steps above, focusing first on network/firewall issues, clearing cache files, and checking the log for more detailed errors. If the issue persists, downgrading to a stable LTS version of Unity might also be a good solution.

Not running any 3rd party antivirus/firewalls, and have disabled all Windows Defender/Firewalls during this process

Having the same exact issue … for all the projects I tried , 2D , 3D , Universal etc …
With the 2022 LTS and also Unity 6 and in the logs there is no error than “Connectivity with IL Post Processor runner cannot be established yet. Retrying.”
I’ve tested in Users folder, another drive, in administrator mode or standard mode, fresh reinstall , nothing worked, so what is the problem with unity ?

For reference, there are some additional pointers and apparent fixes reported by users listed here:

Also check for any “special characters” in the path and this may include spaces if this 3+ years old tip still holds true.

And just in case: installing and running Unity editor in a VM (virtual machine) is not supported and could lead to issues.

Nothing of these seems to work :frowning:

i’m not on a VM but in Windows 11
My graphic card driver is up to date to 566.36
I have a GeForce RTX 2080 SUPER

Here is the log of the editor I can find

Connectivity with IL Post Processor runner cannot be established yet. Retrying.Connectivity with IL Post Processor runner cannot be established yet. Retrying.

It seems that there is no specific error in the log just that it cannot communicate with ILPP

Yup, I don’t see anything else either.

Did you try creating a project with a different template, ie core 3d? Not sure if “3d-cross-platform” is exactly that template.

Did you try disabling antivirus, antimalware, or similar ‘security’ software?

yep i tried the code 3d template, the universal 3d, the learning 2d platformer, the learning FPS quite all of them :frowning:

i have no antivirus installed except windows defender, firewall rules seems to be ok with an entry for unity hub, and editor, so I really don’t know what to do and a bit lost that this issue is there for years now

You mean in general?

I hope you didn’t wait years for a fix in order to use Unity again. Because I can almost (99.9997% sure) guarantee you that if you were to reinstall Windows that issue will be gone. :wink:

Reinstall windows to fix an issue that comes from a software … honnestly i will go on unreal engine ,if they cannot fix their issue that many people have … it’s not professional
Moreover the error is not descriptive ,we cannot connect but we don’t know why , we cannot debug to have the stacktrace or exception or whatever :sweat_smile:

This is just the final solution that I know will work. It’s not necessarily Unity’s fault that a user’s system can’t, won’t or isn’t permitted to launch a certain process. If that issue were widely occuring, there’d be a) a known solution and b) a better error message. But this isn’t the case, it affects a tiny portion of the userbase hence why you find so little information about it.

The “Validation failed” in the Hub occurs way, way more often and even that has no generally accepted solution that works for everyone. This is in part because it has something to do with permissions and security settings/software as it occurs almost exclusively on Windows. The most common fix is to install the Hub and editor from and to standard locations (ie Documents, Program Files), plus wiping any cached downloads - but not even that is a guarantee.

To my knowledge Unity is aware of that validation problem, they even know the 3rd party command line tool causing (most of) these issues, but the circumstances where it fails are largely unknown and not easily reproducible.

The thing is: none of these issues occur on a vanilla Windows installation even for users who previously had that issue after simply reinstalling Windows. That’s telling that the problem lies more on the system side of things than it being Unity’s problem.

I can tell you I had to reinstall Windows because Windows Update stopped working for about 10 times since Windows 7. This is just how brittle Windows is, it degrades until eventually something snaps and things start to fail. And at some point it’s just no longer worth investigating, and you’ll just scrap it once again.

Gladly, it’s no longer as bad as Windows 9x was though. I think I had to reinstall this at least once per year. :wink:
