I'm a new Ubuntu user (I'm just starting out), and after spending hours and hours configuring my system, I noticed that my PC was taking much longer to shut down (not even 5 seconds at first, compared with over two minutes now). I asked some AIs, and they advised me to use the following command to list the various errors since my last boot: journalctl -rb 0 -p 0..3
Here's the output I got:

And please explain them to me! ^^'
Thanks for your help (and sorry if the topic is in the wrong category)!
Edit: I installed Ubuntu by overwriting and permanently deleting Win11. But what is fastboot?
