Bazaar causes conflicts with some other extensions and as far as I know, it's not only me and @peopleinside I never actually got it to work properly, even in Beta 7. It was the very first extension I installed after the update and the entire site crashed. Removed it using Composer and things went back to normal. I usually suggest disabling it and that fixes other users' issues as well. An example is @achlys's post:
I had Bazaar installed previously for testing but it didn't work properly so I disabled the extension.
Not sure if I can provide more specific information on what exactly goes wrong with it.
