I’m getting same error on OJS 3.2.1-4 (not sure if it also happens with last stable).
The fix was published here but I think it was not included in 3.2 branch. If it fixes the issue, would be great if it can be included in last 3.2 stable.
For others falling know in this same issue (while it was added to 3.2 or if you don’t know how to apply the patch), notice it only happens when authors have an orcid AND multilang names. So an obvious workaround is… removing name and givenname in all langs and keep it in ONLY primary language. And in the few cases where this is not possible, you can download the xml, edit (as explained in gitHub) and upload to CrossRef manually.
