tcpdump: (all BPF devices are busy) - How to solve this
I was running tcpdump and then after some time I got this error:
tcpdump: (all BPF devices are busy)
I am not sure why? I killed all tcpdump processes, in case that this had something to do with it, but it did not fix it.

This isn't realy an infosec question, but did you wait long after killing the processes?
In most code this is for the reason it describes - there's not a handle
... honestly, sometimes at that point a reboot is quicker than debugging the 'why' if it's a machine where you can do so, did you do so?
can you ls /dev/bpf* on your host (if that's where they show up? )
For those, have you tried grepping lsof output for them ?
