Lazy theory. Think about cars. If the diversity of alternatives was putting off people, I guess we would still all be driving black Ford cars.
I have been using Linux since 1996 and what is putting off people is:
- First and foremost: habits and lack of will to learn new ways.
- Proprietary apps that have no exact equivalent. See 1.
- A closed proprietary system that limits interoperability. Even if it has improved, certain fenced software perimeters remain an occasional issue.
Buy yourself a second PC or laptop to be able to use both at the same time.
As others said, check if it is a single case or if it repeats at the next shutdowns. Anyway, the main question this brings to mind is: do you have a good backup of your system / data ?
I have fucked up somewhat like you in the past and needed to repair my system. In Linux you can boot into runlevel 1, single-user mode, where you are effectively root and can remove the root password, the re-enter one after you boot in the usual runlevel again. See these links: https://www.debuntu.org/how-to-recover-root-password-under-linux-with-single-user-mode/ https://www.debuntu.org/how-to-change-boot-runlevel-with-grub2/ https://www.geeksforgeeks.org/run-levels-linux/
The sources.list contains a list of the sources that can be used for the installation and update of software packages. If you installed your Debian Linux distribution from a CD/DVD at some point, or maybe just by default if there is a CD/DVD player in your PC, an entry will have been added to the sources.list file corresponding to the mount point of the installation CD/DVD. Usually you can deactivate this entry after the initial installation, as I suppose that you further installs and updates will be from network sources. The full path to the location of the file is /etc/apt/sources.list. You can edit the file in a text editor, but as a newbie it is probably easier and safer to do that via your graphical update/package manager. Have fun discovering Linux.

The original Leisure Suit Larry series, Monkey Island, Day of the Tentacle, Myst, Half-life, Doom, Quake, Lemmings, … For more fire up your retropie or recalbox on a raspberry pi.
I use the Notes app of Nextcloud. It syncs flawlessly between Linux and Android. Of course with your own instance of Nextcloud, hosted or self-hosted, you get sooo much more.
