Mac beta 8.5.0.83, QR scanner doesn't appear in any context

It was a false alarm, the problem was not with 1Password. Both the app and the browser plugins for Safari and Firefox were failing to detect a QR code that was present on the screen, but it was probably because the QR code contained incomprehensible information: the code was just for downloading a Synology authenticator app. After obtaining that app, the site displayed the real QR code for 2FA and 1Password correctly found it. So for anyone finding this in the far future, in at least this case, if 1Password encounters a QR code that isn’t recognized as useful, it won’t report the issue beyond saying it didn’t find a code. Like flatly reporting it did not find an elephant in your bedroom and not mentioning that there is however a large tiger in there.
