I was working on an FL Studio project and added Scaler 3 with Nexus 5 as an instrument inside Scaler. Both plugins are vst3. I saved the project, but now when I open the project, it crashes FL and closes the DAW upon initiating Scaler without any error notice. I ran the FL Diagnostics tool, took out Scaler, and the recovered project (without Scaler 3) opens fine.
Working in reverse, I also ran the FL Diagnostics tool and removed every instrument & FX plugin except Scaler, then recovered the file. The recovered file crashed on open just like the original project. Here’s the project with nothing except Scaler 3 on it that crashes FL.
