Hi, nothing triggers me but, snap seems to take a long time to load. Do you use it? if not you can opt to to disable it.

  Alert: No Swap data was found. 

some swap might be usefull, even if it almost never used. Swap - Manjaro

Depending on how long you are running with this install, do some maintenance?
