Running into the exact same issue here, this is preventing us from moving our game to the App Bundle system.

Same here

Thanks everyone for reporting this.
I've confirmed the issue on IL2CPP builds on 2020.3.14f1.
I'll investigate today and try to make a workaround available as soon as I can.

I've found a potential fix.
Unity versions 2020 and above crash if the "assets/bin/Data/Managed" folder does not exist in the base apk.

The snippet below adds an empty file in that directory to keep that folder in the final App Bundle.

var managedDirInfo = Directory.CreateDirectory(Path.Combine(baseDestination.FullName, "assets/bin/Data/Managed"));
File.Create(Path.Combine(managedDirInfo.FullName, ".keep_folder"));

If you add that snippet after this line, you should be able to build App Bundles that do not crash at start up.

@zheka20012, could you see if that workaround fixes the issue?

Just a heads up, that results in this error when building:

Can fix that by appending a Close() call on the File.Create, so the line becomes:
File.Create(Path.Combine(managedDirInfo.FullName, ".keep_folder")).Close();

Still pending testing whether this fixes the crash.

[zheka20012]

Nice, looks like that fixed the issue

[jamcohen]

Thank you both for testing the workaround, and @Clavus for the .Close() correction.
I'll put together a proper fix and make sure it's included in the next release.

var requiredDirInfo = Directory.CreateDirectory(requiredDirPath);
