Bug Android il2cpp build fails due to System.IO.DirectoryNotFoundException on 2020.3.20f1

Greetings, I have been having this problem for several days. I am trying to publish on Google Play but when trying to generate the .aab file it shows me the following errors:

DirectoryNotFoundException: Could not find a part of the path 'E:\Workspace\Unity\Enchanted Duels\Temp\StagingArea\Il2Cpp\il2cppOutput\Data\Metadata'.

If I choose Mono I can correctly generate the .apk file, but with IL2CPP I cannot generate either the apk or the abb

 

Android build not building:

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.

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 that subsystem.

 

Blank project build succesfully.
I will review each part of the project following your instructions, thank you very much!
