I just updated to 24.6.1 as well and noticed the same thing. I filed a bug report through Adrenalin already. This has happened in the past on earlier drivers, but I could always fix it. The steps to do so back then were:
1. Boot into Bios and disable "Re-Size BAR Support" and "Above 4G Decoding," then reboot.
2. Once into Windows, reboot into BIOS again and re-enable those options, then reboot.
3. Once back into Windows, it should pop up a notice of a hardware change, prompting another reboot.
4. Reboot one last time into Windows, and SAM would then be available again in Adrenalin.
Trying those steps now are no longer working.
