Status=Error: Failed to capture tab: image readback failed ###

I am running a headless server, using the Edge browser on Windows 10. I only log in to trouble shoot and make adjustments, so 99% of the time Ui.Vision is running without a monitor. That said this particular error is inconsistent, occurring when I manually run the Macro and when it is executed via a batch file via the windows scheduler. I would say it happens once a week, but not consistently at a certain date / time that I can pin down, and across different Macros.

Anyone have any ideas for what causes this specific error?

Here is an example Error Log:

Status=Error: Failed to capture tab: image readback failed

[status] Playing macro ImportCSV_Inv_GS

[error] Failed to capture tab: image readback failed

Is it truly headless (no GUI)? Or is there a user logged in, just no monitor connected?

I access the pc via splashtop.
