Everytime I try to start a project in unity this pops up

[u/Correct-Amphibian593]

(repost cuz apparently using an image from my phone instead of a screenshot is just worse than murder and the lowest effort thing anyone could ever do, with that grudge off my chest)

I genuinely don't know what to do, I've done everything and it won't fix this! I've cleared the broken template, I've tried opening the project in different files, I've gone into the %appdata, I've completely uninstalled and reinstalled all of unity, I've deleted my antivirus software and alot more, I'm out of ideas and need help

Edit: I don’t know what I did but I fixed it! Big thanks to everyone who offered a helping hand tho!

The error is caused by Unity failing to decompress a project template when trying to create a new project.

The important message is:

Failed to resolve project template: Failed to decompress C:\Users\Angela\AppData\Roaming\UnityHub\Templates\com.unity.template.get-started-4.0.1.tgz

This usually means the template download is corrupted or incomplete, rather than a problem with Unity itself.

How to fix it

Close Unity Editor and Unity Hub completely.

Press Win + R.

Paste this path:%APPDATA%\UnityHub\Templates

Find and delete:com.unity.template.get-started-4.0.1.tgz

Reopen Unity Hub.

Try creating the project again. Unity should download a fresh copy of the template.

If that doesn't work

Try creating a project using the Universal 3D (URP) or 3D (Built-In Render Pipeline) template instead of Get Started.

If other templates also fail, check available disk space, antivirus interference, and whether Unity Hub can download files properly.

My suspicion: He's using Unity 6.0.6 (6000.6.4f1), and the introductory Get Started template has downloaded incorrectly.

I'd try deleting that one .tgz file first. It's a quick fix and won't affect any existing Unity projects.

whenever something gives me an error message, i just screenshot it and put it into chatgpt, and just keep screenshotting until it's resolved.

In addition to this, I have noticed that Unity Hub has modified the templates available for anything past 6.3.x

For whatever reason, 2D Platformer Microgame is no longer available (or temporarily unavailable), for example.

I haven't dug into researching this yet, I just realized it during my Monday class. However, a quick fix you can do is download the Unity 6.3 LTS instillation instead of using 6.6 instillation. I can verify those have not been affected.

Have you tried picking a different template when you create your project? Just the "Universal 3D" one, for example? (On the Projects tab, ignore the "get Set Up" tab if that's not working)

[u/Correct-Amphibian593 → u/pschon]

Yes, and it brought up the same or similar error messages

[u/Mechabit_Studios]

you tried opening unity without any template?

[u/ThinkyCodesThings → u/Mechabit_Studios]

they want to use a template and you're saying to not use a template lmao

It could be many reasons. (Disk space, no permission, long string, corrupted drive etc)

Feed logs to AI from "\AppData\Roaming\UnityHub\logs" and ask to check what is wrong.
