Bug Unable to Build my projects

Hello!
I'm following Unity Tutorials and trying to build my projects to share them (as suggested by the tutorials themselves).
Sadly I appear not to be able to do so ):
I even tried to build an empty project and still it wouldn't let me build it.
I'll attach a screen of the errors.
How may I solve this problem?

Thank you in advance for the help!

 

How to troubleshoot build failures:

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

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

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

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.

Android build not building:

Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

https://forum.unity.com/threads/cant-build-for-android.1306098/

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

Android Gradle errors and other related stuff:

I'm in the first case, I reinstalled the version of Unity (last LTS available, (2021.3.16f1) and it still doesen't let me build.
How do I solve the issue?

 

Recheck your installation process, make sure everything is set up, reboot your machine, etc.

If you can't get it working, try a different LTS version.

 

Just reinstalled again the "recommended" version and still can't manage to build an empty file...
Do I really have to switch version?

 

You don't really "have to" do anything, I'm simply listing things that have worked for me and others.

 

Well, if there is a way to make the recommended version work I'd be really happy to do so!
If you think it could help, tomorrow I'll be available also for calls

 

Click on that first error -- the one with STDOUT. It probably has more lines of text.

The console will only show two lines from each error.

 

Sure, it says:
"Internal build system error. Backend exited with code 2.

But I don't really know how to use that in order to solve this problem.
Also, the following one talks about stuff going on in the PostProcess, but still don't know what to do about it (I've already tried to mess around with postProcess settings and disabling it, but still nothing happens)
