Circle is always spinning in the latest Android version, 1.4.3.0950. I'm using MM on many Android devices, but this problem exists only on Samusng S22 Ultra, under Android 12. It also drains battery like there is no tomorrow. I have a relatively large collection of music, at around 10k songs. Please let me know if you need more info on this.
So far I tried to re-install the MM, rebooting the phone, killing the background scan process and MM itself but it doesn't really help.
