Let me move this to the Bridge forum for you, where you are more likely to receive an answer to your question.

Due to huge mistake in the last update you now have to downgrade CR to 12.2.1 AND Bridge to 10.0.4 to get back the functionality you had
For Bridge 10.1.0 & 10.1.1 , minimum required version of camera raw is 12.3. So if you want to use ACR 12.2.1, you would need to install Bridge 10.0.4. We are working on making future Bridge versions backward compatible with older versions of ACR.
That's not a great idea. One more thing to break. There are plenty of other bugs in Bridge that need attention.
Please confirm that there will be fast action to fix the multiple issues with the ACR UI in 12.3? I the meantime I will need to remain Legacy with 12.2.1 as I am unable to work with 12.3
