Hi @Sturek, welcome to the forum. Please delete the Scaler 3 .settings state file, then restart your machine and see if that resolves the issue.

Hi @fcarosone and @hed0rah
Given your reports, it might be worthwhile doing a clean install of Scaler 3.2. Instructions can be found at the bottom of this thread. If the issue persists, please let us know. If possible, providing a Cubase crash report would be very helpful for our devs to investigate further.
