Fatal Error - could not create required lock file - MacOS 13.5

[Trebz]

Roon Core Machine

MacOS 13.5 (MacStudio, M1 Max, 64GB) running Roon server.
Issue is with start up of Roon app to use as client to play on same machine.

I ran into this issue, and ran the terminal commands listed in this post, but it did not help.

Fatal Error - could not create required lock file

That worked!!! I would have never figured that one out!!! Thank you Marc!

I am able to start music by using my iPhone.

I am not sure if this issue is because I closed it and reopened it too fast, or if the MacOS 13.5 update I did today broke it.

I can no longer open Roon - but it did say I was running the latest version as of an hour ago.

Networking Gear & Setup Details

Description of Issue

When opening Roon as a client to play music from the Roon Server on the same machine, I get an error “Fatal Error - Could not create required lock file”

OK. Ran the command a few more times to no avail. But then killed Roon again, and ran the terminal commands from the other thread, and rebooted and I am in business.
