@ToKe From what I see here, there are some prob;ems with content manager, pretty much ending callouts. After this, your games begins to force you to go off duty.
I'm researching as much as possible, but haven't found much. I don't personally know the fix, but I'm trying to see if others have had the same problem had solved the issue.
StartCallout: There's already a callout running. Aborting...
LSPD First Response: EndCurrentCallout: Finishing...

Then you forced duty and it seems to be fine with no errors.
Traffic Policer & PoliceSmartRadio both haven't been updated, so I suggest removing those as it could cause issues, possibly issues you're facing.
I'm going to keep looking, but this is as far as my knowledge goes. As a last resort, un-install all plugins or even LSPDFR itself and reinstall.
