Bluetooth can't enable in KDE Plasma

[epistomai]

Bluetooth was working more than a week ago. Every time I turn on, it is like this:

systemctl status bluetooth                                                               ✔

Although I use # rfkill unblock bluetooth, it actually unblocks, but still cannot enable in Plasma:

I tried with different kernels, so far 6.19, 6.18, 6.17, 6.12 and none of them seems to work. I also plugged the bluetooth dongle in my Laptop with the same Manjaro kernels and working smooth.

Is there some app that can be blocking it? I had another issue with the AMD GPU that already solved, I am not really sure if the last update broke many things or something else.

The command to unblock is

rfkill unblock bluetooth

The command is a user space command - root is not necessary.

Personally I cannot reproduce it, I use a bluetooth dongle on my workstation to connect a bluetooth headset (Apple), and it work without any issues

I should have said that first have the issue with an ASUS BT500 dongle, after unblocking the internal (Intel AX200) it worked for a couple of days, but stopped working and same issue. I dig into a lot of forums (I usually look in Arch) and couldn’t find anything. I also commit blasphemy asking AI and nothing. I just had to dig somewhere in a supposedly missing file, but I belive the last major update came into conflict with drivers for bluetooth in general. Anyway, I just look in the aur and found someone posted an old driver (rtl8761b-firmware) because of conflicts with new updates or something. I don’t think any regular user could find this, but just installing and overriding the driver, works as expected.

I usually wait until manjaro team fixes these issues, I’ve become so lazy. But this time was driving me nutz. Hope it works for those with the same issue
