Hello this afternoon I was trying to get the apk file and I get an error but it does not specify which one
The same error was reported here

Does your app contain any extensions? Some apps using extensions fail on release version nb 184 (because some extension developers extensions have issues with Google's latest requirements). You can make a copy of your app and delete an extension and see whether the copy compiles... what happens?
Without more information about your app... file sizes, names etc and knowing whether this app previously compiled ok any advice is guess work. Some of your Media files have long and unusual file names. Sometimes very long file names create issues. Is this your problem? We do not know.
This type of error is extremely difficult to diagnose without a Bloc image or an aia available to review
