Program closes when sent to render in Encoder

Hi, I have version 24.1.0, and since the last version, I have a strange bug. I have two monitors and the way I customized my workspace is that on the right monitor, I have the program window where I have my video preview/playback. But when I send the sequence to render, the program monitor closes, ok, it happened before, but when I went back to "edit" tab, the monitor was back again as my workspace should be. but not anymore! now when I go back, it doesn't appear anymore. to see it again I should switch the workspace to anything else, like, audio or effects workspace, and then right back again to my saved one, then the program window appears again.
It happens in the new beta version as well.
Thanks!
