Bluetooth suddenly stopped to work with 22.04 on Dell XPS 13 9310

[nils-vldj]

I've been using Ubuntu for more than one year without any problem. But now I'm facing two ! I was able to normally turn ON/OFF my bluetooth and to connect my computer to any device. But now, if the bluetooth parameter is still available, there is no way I can turn it ON. The switcher switcher, but does not turn orange and the bluetooth stays OFF.
I tried to boot on a flas drive with Ubuntu on it, the problem was the same : the bluetooth did not work (but I didn't face any sleep mode-wake up issue).
I do not understand, since my bluetooth used to work until now...
What can I do to get it back working ?
Thanks in advance for your help, nils This is what I tried without any good result : (My bluetooth device is ON in the BIOS menu)

I had the same issue on Ubuntu 20.04. Bluetooth just unexpectedly stopped working after the reboot. Then I realized that Ubuntu silently installed some updates (and kernel update among them). So, I just booted from previous kernel version and Bluetooth is working again. So, it seems that it's a recent kernel issue.
