Izotope Neutron 4 glitching in renders

Hi there - I’m getting a glitch at about the 1 second mark in renders of each clip from a 48k montage with Izotope Neutron 4 instantiated in the Montage Output pane. Clips play fine within the montage, but glitch when rendered. Plug In Warm Up makes no difference, nor do any of the “Reset Plug-ins” options or the “Performance” options. This is on a smoothly operating MacStudio / Ventura 13.4.1 / Wavelab 12.0.2.

Any ideas how I might fix this?

Thanks!

Usually contacting iZotope is the solution.
