Unable to efile California amended individual return

We are getting an error message when trying to efile a 2022 California individual amended.  The error relates to "A binary attachment file".  I called Proseries and they have not addressed this issue and recommended we file a paper copy with CA.  It appears this error has been around since 2021 (based on my search in this Accountants Community).  Does anyone have a work around to get a 2022 California individual amended return to efile and get accepted?

 Are you attempting to attach a PDF to either the fed or state return?  Or did you attach something with the original returns?

Original Fed and CA returns had pdf attachments.  Federal amended was efiled and accepted with no problems.  I have tried efiling CA amended with and without attachments and get the same "binary attachment" error.
