Hi @pidul,
Thank you for sending the logs.
Could you please check in the Windows display settings if there’s a detached second display and just attach it by selecting Extend or DUplicate underneath Multiple displays dropdown menu.
If there’s no detached display, do you maybe have Nvidia ShadowPlay/In-game overlay/screen recording enabled in your Nvidia Geforce Experience settings?
If yes, please disable it (maybe reboot afterwards) and try again with spacedesk.
