Windows 11 Efficiency Mode will cause 'Unable to start Rendering Engine'

Hi team,

Im doing work on pillar candles. I downloaded the pillar candle asset from the assest library. I apply an image to wrap around the candle, and there is always a slight line cutting through the graphic. I thought this was maybe a viewpoint percentage problem so I adjust from say 78.9% to 80% to round it up (which doesn't save in the file btw), to no avail.

I render Ultra / Real time.

Its also in the design view. Its always at the exact same spot no matter what I try. Is it a problem with the assest perhaps or something to do with the wrapping engine, or maybe my graphics card.

Images below. You can see a slight black line down the candle. Thanks team.

Windows 11 / Stager 2.1.4
