Cant find 9patch chunk in file

I faced an error while decompiling one of the Android 13 apks.

Press any key to continue . . .

I am using the updated 2.8.1 version of the Apktool.

Will wait for the response.
Thank You

This looks like expected behavior. If we cannot detect 9patch chunk data - we treat it as a regular png.
