I was able to solve the bug in the end. As I was trying to start plasmashell from the terminal, I noticed that there were errors about some applet having an invalid with. This was weird, because the only Desktop applet I used was two taskbars with petty usual configurations.
Anyway, I just needed to reset my Desktop with rm ~/.config/plasma-org.kde.plasma.desktop-appletsrc, rm ~/.config/plasmashellrc and rebuild it.
