I'm on Catalina 10.15.7 with a 13" 2019 MacBook Pro. Upon wake, I now always see the beach ball of death. There is never anything in "Spin Reports" under console. Lots of these messages:
Service exited due to SIGKILL | sent by mds - 239 since wake. However these continue throughout the day.
I've noticed a few times there is a crash of a piece of software - SACSrv or com.apple.WebKit.WebContent. But many times there is no correlation.
