Suspend/Hibernate works only a coulpe of times

Usually, after restarting, I can run

systemctl suspend

once or twice, after which, it gives me an error:

Failed to suspend system via logind: There's already a shutdown or sleep operation in progress

The only thing I can find in

journalctl -r

is this:

The freezing tasks bit is the only hopeful thing there is, but I don’t know where to go from here.
