@Troglo37 ,
It’s much too late now, but for “open all tabs”, Notepad++ has the session.xml.inCaseOfCorruption.bak, which should be one version of your session file out of date (for example, my session file is dated yesterday at 7:13pm, and my corruption-backup is from 2:37pm that same day). So, in the future, if you open Notepad++, and it doesn’t have all your old session files open, before doing anything (before closing Notepad++ or trying to save or load anything), make a copy of session.xml.inCaseOfCorruption.bak to tryme.session.xml so it won’t be overwritten, exit Notepad++, rename session.xml to bad-session.xml, copy tryme.session.xml to session.xml, and start Notepad++: that should take your in-case-of-corruption session as your active session … so if the previous time you exited and started was good, you should be back to that session.
That won’t fix your corrupted stylers (colors). Unless you had a recent change in one off your Style Configurator settings, I am surprised Notepad++ was trying to write to your stylers.xml, because it only tries to write it if there was a change. But maybe the reboot process confused some bit in memory making Notepad++ think it needed to.
