I've created backup rules file just like in example https://developer.android.com/guide/topics/data/autobackup:

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content xmlns:android="http://schemas.android.com/apk/res/android">
 <include
 domain="sharedpref"
 path="." />
 <exclude
 domain="sharedpref"
 path="nonceStorage.xml" />
 <exclude
 domain="sharedpref"
 path="localStorage.xml" />
</full-backup-content>

and Android Studio say's that there are errors:

Error:(8, 15) `nonceStorage.xml` is not in an included path [FullBackupContent]
Error:(11, 15) `localStorage.xml` is not in an included path [FullBackupContent]

Error message is totally uninformative and not googleable (almost all words are very short).
Can anyone explain,what does this *** want from me? How to fix this issue?

the error message tells, that there are no such files to exclude in domain sharedpref:

Error:(8, 15) `nonceStorage.xml` is not in an included path [FullBackupContent]
Error:(11, 15) `localStorage.xml` is not in an included path [FullBackupContent]

possibly it is domain root - but while not including that domain, no need to exclude them.

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content
 xmlns:android="http://schemas.android.com/apk/res/android">

 <include domain="sharedpref" path="."/>

</full-backup-content>

use the "Device File Explorer" and go to /data/user/0/com.yourapp/shared_prefs ...

there you can see which files belong into which domain - or if they are even present there.

I guess this is an IDE bug because the example from doc:

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content>
 <include domain="sharedpref" path="."/>
 <exclude domain="sharedpref" path="device.xml"/>
</full-backup-content>

shows the same error on device.xml.

Removing the <include> clears the error if you simply want to exclude some files because the doc says

By default, Auto Backup includes almost all app files.
