There is a new build going out today that should have the fix, Current Channel Version 2212 Build 15928.20216. It's not listed on Update History yet but should be later today, Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Learn.
To install the build from Outlook, click File, Office Account, Update Options, Update Now. I have not had a chance to test it yet. Please try it and let me know if it works or not.
