Apologies I did review your original post and share it with the Local team but we just haven’t been able to dig in and do any extensive testing yet regarding that specific issue. That said we don’t really have any bugs around export/import. Doing simple tests with this function on my end throughout today and all works fine.
The screenshot you shared of the plugins all missing and throwing an error I did see recently with someone else I was helping with an import. The solution was to remove various core files, backup files, etc that they had in their zip before trying to import it into Local again. I can appreciate that this export was created in Local, so that might be a bit on us to look into ways to ensure exports created in Local are easier to reimport. I noticed however that you have an updraft plugin for example. So is there a chance in your site example above that you have extra site backups, DB backups or core files saved within the zip you’re trying to reimport?
