I have not being able to reproduce your issue. Can you give us more information about your issue and the modifications you performed on your site? I installed the 4.0 version of the plugin for Drupal 8 from the link below in a fresh new instance, created a database backup and restore it without issues.
Apart from that, I see the error message below several times on your bnsupport bundle. Can you tell us which version of the module have you installed? Did you find any issue installing it? Did you install and/or enable any other module? This error message can be related to a module not being properly installed/uninstalled from your site.
