Fedora Silverblue (sericea). After rpm-ostree update, lost the bluetooth functionality (BCM2046B1)

I have a mid-2012 Macbook-Pro, and installing the Fedora Sericea 38 the Bluetooth works out-of-the-box. (Sericea version 38.1.6).
After upgrading through rpm-ostree update (current version: 38.20230727.0), I lost the Bluetooth functionality entirely, taking them back only when I roll back to the original release version.
I don’t know even what I can try for managing to have. Is there anyone have some idea?

Might be similar to "No Bluetooth Found" after upgrade from 6.3.12 to 6.4.4

I don’t know if is related because at the Fedora 38 (not the immutable, but the retail one) the Bluetooth functionality doesn’t get broken after a full update.

But, anyway, following as asked in your thread, follows some data before and after updating the immutable image with rpm-ostree update.

I believe just worth mentioning that I have the broadcom-wl package layered in my installation for having my Broadcom BCM4331 Wireless card properly working. I already tested with and without this package layered and does not like having any relation with the Bluetooth functionality.

Follows the data before and after updating.

Before the update, at the given version 38.1.6 (2023-04-13T19:03:58Z).
(Just refreshing that at that version, the Bluetooth functionality works as intended.)

I hope this information helps to find somehow what is coming on.

There is no such thing as “Retail Fedora”

Ok. Sorry about my misspelling. What I tried to say as “retail” was just referring to the “Fedora 38”. The main release or the default release. Not any spin or the immutable version like Silverblue or Kinoite, but just “Fedora 38”.
What would be the proper way to refer to it to differentiate it from the others?
I also would like to know if you have any advice to fix my issue with the “Bluetooth”. There’s any? Because I believe it’s important to keep up with the main subject for this topic.
So far, thank you for your comment.
