Core Logs Not Populating

I have noticed my Core Logs are not getting any entries. I would often get a few a day.
I do get entries on startup but once it’s up and running I get no more.

homeassistant.log does have the startup entries but no more after that.

I have filters in my logger, I’ve commented them out and it is still the same.

I have tried a system_log.write service call but that does not appear either

Tried deleting the log files and restarting, they are recreated and startup entries appear.

All other logs are working fine

Any ideas ?

EDIT: SOLVED - was the UK Bin Custom Component, they fixed it so all is good now
