Hello to everybody,
yesterday I wanted to move some files to an old external HDD. Before moving the files, I deleted any existing partitions and changed the filesystem to btrfs using KDE Partition Manager. I formatted it by changing the drive name to Data_2 and mount point to / run / media / andrea / Data_2.
Everything seemed to work fine, so I repeated the whole operation with another external HDD, calling it Data_3 and mount point / run / media / andrea / Data_3.
No error message, the PC shutdown went smoothly.
Today, when I turn on my PC, I notice that the startup is particularly slow. After more than a minute and a half (usually it takes no more than 15 seconds) the system goes into emergency mode:
You are in emergency mode. After logging in, type “journal -xb” to view system logs, “systemctl reboot” to reboot, “systemctl default” or “exit” to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):
Then I reboot the system, I try to use another kernel (linux-lts) but nothing changes. So I boot from a timeshift snapshop. This time, finally, the boot is successful.
I have made multiple booting attempts, checking the output of journalctl -b -1 each time.
This is an example of a suspicious error:

I am sure that, in previous boot attempts, the output of journalctl -b -1 contained the same type of error referring to the Data_2 and Data_3 drives.

Is booting into emergency mode caused by these errors? How can I go about solving?
Thank you in advance for your help!
