Sometimes shutdown takes a long time

since the latest update,every second day it takes the Laptop around a minute to shutdown.(weird;one day okay,the second not).
and two shutdowns ago i got a wall of text while shutting down.
i tried to look this morning in the journal logs,and searched a bit for some suspect logs i saw before shutdown and they brought me to what looks similar to my issue:
but i have no real idea of what’s going on.

please let me know what input should i provide.
