15 seconds delay until next track begins playing for local files

The problem is still happening on a regular basis. After a restart of the Roon Core everything works perfect for 10-12 hours. Then i get the huge delays when i want to start the playback of the next track in an album or the first track in a new album.
The delay goes up to 24 seconds. The same “Computed stats” entry repeats many times before the playback begins. In the below sample form the logfile it was repeated 17 times.
This looks like a bug to me.
Since i am a new Roon user i don´t know what i can expect from #support.
The ticked was created 17 days ago, but until now there was no reaction from a technical support member. How long do i have to wait until there is a first response from the support team?
