First, make a blank project with a single blank scene and prove that it builds successfully.

If it does NOT build, then go fix your Unity installation, or your other tools, such as Android SDK, NDK, JDK, etc.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

https://forum.unity.com/threads/aab...y-2021-3-8-with-jdk-1-8.1322211/#post-8551193

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

 

This is a Windows 10 build.

 

Everything above still stands. The android setup part is simply an example. If you can't build a blank project, why waste time until that works?

 

This is a brand-new clean project.

 

It sounds like perhaps you haven't installed software before. Sometimes a particular version of software will not function, for any number of ten billion different reasons: operating system problems, corrupted files, version incompatibilities, etc.

The reasons are manifold and irrelevant.

At the point you have reached, traditionally one would reach for first a complete reinstall of the software. If that does not work, then one would reach for a different version of the software.

I have a very similar issue with Unity 2021.3.13. Just I am doing it with my project (not blank I mean). The error logs don't provide helpful information. Can you give me a direction to research?

• Windows 10.
• IL2CPP enabled
• .NET Standard 2.1

Oh nice, I just post my reply before scrolling to the message. Thanks!
Waiting for a fix from Unity...

 

Sounds great! Let me try.

 

It works. Thanks!

 

Thanks, this is working on 2022.3.11f .
