A bug was reported for this already here:
>
>
> The Player's status.json is corrupted, for example:
> {
> "lastActivity": "08/04/2020 08:31:17",
> "state": "Running",
> "xmdsLastActivity": "01/01/0001 00:00:00",
> "xmdsCollectInterval": "60"
> }}" : "60"
> }
It will be fixed in the next release.

Hi Alex,
When is the next release to fix this? Or how do I supress on a player until the fix is released?
My environment is Spring Signage CMS with white label windows player.

Very soon. Hopefully early next week. In the interim, you can either remove the extra `: "60" }` from the json file, although it may well come back, or disable the Watchdog temporarily by stopping the Player and the Watchdog, renaming the executable in the installation directory, then starting the Player again.
