I had this happen to me a while back. It seems like there was something wrong in the know_devices.yaml file. If you made a modification to that file check your syntax, etc. Otherwise you could try deleting that file and let it get recreated and populatured by the device tracker.

I deleted that file. But it’s not recreating it again

Have you rebooted HA after deleting the file?
