May I have a video or screenshot of the issue?
And can you screenshot your Windows update history from June?
Please double check if you have try to run the Screenpad Optimizer
If it still doesn't work, please follow below FAQ to reinstall all the related drivers in orders.
Have you tried to press Win+P to switch different project mode?
Yours looks like "duplicate". How about switching to "extend"?
Or press Win+D after rebooting the screenpad.
And I did not see the control center/toolbar showing up on the screenpad.
Please refer to below link, hope it works.
If it sill doesn't work. Can you record a video of how the screenpad looks like when first booting up?
You can use F6 turn off and then on the screenpad.
