Archives fail w long filenames

I've tried creating a .dra of a finished project by "Exporting Archive," and it failed several times at various files with long or unique filenames. Maybe it's specific characters in the filename causing it to fail? Also tried "Media Management" and tried copying all the files in my finish project's timeline to another drive. It went overnight, was 85% complete and failed at another long filename. Why is Resolve's media management/archiving so sensitive? If I can import a clip/file into my bin, shouldn't Resolve be able to copy it to an archive? I now have to way to create an archive or media manage the timeline due to these issues. Is there a work-around? A fix? Im using the lastest version of Resolve 16. Havent upgraded bc I was finishing this project, and I've upgraded early in the past and been crippled by bugs.
