Ubuntu 21.10 bluetooth not working after resuming from suspension. Only restart fixes it

When I suspend my machine and then I resume it, under both Ubuntu 21.10 and Pop!_OS 21.10, the bluetooth disappears, as shown in the following images: It's like there is no bluetooth card in my pc. The only thing that fixes it is a restart. Looking online this seems to be a common problem. I tried all the solutions I could find. Some older post attributed the problem to an old buggy version of bluez, but on my machine I have the latest version: gerardozinno@pop-os:~$ dpkg --status bluez | grep '^Version:' Version: 5.60-0ubuntu2.1 I tried the solution suggested here https://askubuntu.com/questi
