David, can you also please include the full engine's log? Thanks!
Maor - note that this was reported against 3.6.9.
I have a vague recollection you already handled something like this in 4, but please take a look?
Please attach the engine logs
Closing this for now due to insufficient info.
It looks like there were async tasks which were still running but from the logs there is not enough information what was running and the context.
I've tried to reproduce this on my env and it seems to work.
Please feel free to re-open once there will be any additional data
