Ubuntu 22.04 - Delay in keystrokes on Bluetooth keyboard

The problem:

I've been using Ubuntu 22.04 for a few months now, and I use the Logitech K380 keyboard which has always worked perfectly. However, a few days ago I started having problems with delayed and/or repeated keystrokes, and I noticed that the delay varies, being greater or lesser depending on the moment. I've tested the same keyboard on another laptop (one with Mac OSX), and it works perfectly on that one. On the laptop with Ubuntu, the integrated keyboard also works perfectly.

Other information:

• I use Redmi Airdots 3 earphones and they work very well;
• I have two other earphones that also work well;
• Note that I've been using this keyboard here for months without any problems... I also used it on Ubuntu 20.04 before and had no problems either.

What I've tried so far?

Not much, just uninstalling and reinstalling Bluetooth:

➜ sudo apt-get remove --purge bluetooth
➜ sudo apt-get remove --purge gnome-bluetooth
➜ sudo apt-get remove --purge bluez
➜ sudo apt-get remove --purge bluez-tools
➜ sudo apt autoremove
➜ sudo rm -rf /var/lib/bluetooth/
➜ sudo rm -rf /etc/bluetooth

After that, I restarted the computer and reversed the process, installing the packages I uninstalled.
