and everything could be working for weeks without and issue and suddenly I get this massive delays

tried running

$ sudo systemctl restart prefect-worker

this did not appear to help Tried to go to “Work Pools” -> “default-agent-pool” -> “Work Queue” pause and start the work queue it was healthy before and healthy ofter, but still none of the pending flows make any attempt to run

pip3 install --upgrade prefect

also did not help

Deleting the pending flows and rerunning them appears to be working, but not an optimal solution
