I've just switched machines from a recent 13" Mac Book Pro to a recent 16" Mac Book Pro. I have three screens, the main retina screen, an additional 24" screen connected through Thunderbolt, and an older iPad as sidecar, connected by a cable. The third display is normally the screen where I have OBS Studio sitting.
After switching boxes, I had issues with OBS Studio not showing any of my scenes at all. So I removed OBS Studio and all affiliated files and reinstalled OBS Studio (27.0.0) from scratch. I reimported my scenes but since my former setup recommended a smaller resolution, I have revised all those scenes. All seems to work fine again.
But when I try to move the OBS window to the sidecar screen, the preview shows two instead of one frame and freezes. OBS seems to keep working, apart from the preview. If I deactivate the preview, things keep working. As soon as I reactivate the preview on the sidecar, OBS Studio crashes with the given log:

It used to work with my old box. Do you have any ideas what might be the reason?
