bluetoothctl doesn't work anymore

I need the help of someone with more experience than me. Bluetoothctl doesn't work anymore. When I try to power it on, it says: "No default controller available".

journalctl says:

From research I found people with the same problem, but I couldn't find a way to fix it.

I do think that is a hardware issue. Try some other flavor of linux like ubuntu, if bluetooth works in that, we can say for sure its a kernel or bluez issue.

If other linux destro is not available, U can try installing old kernel or LTS kernel, if that do fix your issue. This means that something changed with the drivers for your bluetooth hardware that breaks it. You can file a bug report or keep compiling your own kernel with that commit reverted.

From the logs I do strongly believe bluez is not to blame at all. I have seen this in an old laptop in which bluetooth works for some time after this similar errors come like hci0 command timeout etc..
