My preview windows on AE is suddenly completely empty

[mg88633778]

I can view all my layer controls but not my layers. Have uninstalled DUIK uninstalled and reinstalled AE, and tried various resolutions. Nothing. Any ideas? Running a 2015 Quad i7 Imac with 32GB RAM and 4gb GPU. Not the quickest, but surely it can handle this.

The unusual aspect ratio may simply throw GPU acceleration out of wack. Start by disabling GPU usage and see if it makes a difference. Otherwise it could be DUIK's crappy code making a mess and causing soem resource issue in the expressions engine, so selectively turn off those expressions and see if the layers reappear.
