For fun, I am going to present a series of alternatives, reply your favorite:

: Kayla has left/is leaving him

: He failed a drug test

: He violated probation in some other way. Not relating to drugs or alcohol

: Miscellaneous "family emergency": something genuinely not his fault. Kayla got into a car accident or an elderly family member fell down. That kind of thing

:He just didn't feel like streaming

:He has been alerted that the bodycam footage has been released!
Edit: Added some clarification/Added 6th option
Edit again: Assigning to ratings
