1 PC multi session issue

Hi,
I created my settings like https://xibo.org.uk/docs/setup/windows-player-multi-install.

First client working correctly for 3 videos loop.
But, Second client’s player is closed when first video is ending. 1 - 2 minute later, watchdog restart player.

I use Version 2.1.2 CMS and xibo client v2-R201
Thanks.
