I’m on a Mac 11.6.1 and I use a Trash can 12 core 128GB ram machine
In the finder, option click the “Go” menu and select “Library.” Then navigate to the Preferences folder and find Nuendo 11. Drag it to the desktop and restart Nuendo. The prefs will rebuild. You’ll lose all of your previous settings, but if that works as an iZotope fix you can replace the files from your old settings bit by bit. Or you can restore a known good set of prefs from a backup in Time Machine.
But I’d probably try uninstalling and re-installing RX 9 first.

Don’t just bin them. Copy and save the preferences folder somewhere as you may find deleting them doesn’t fix the issue and you’ll have the pain of resetting/rebuilding everything for no gain.
Of course. That’s why I suggested moving them to the desktop rather than trashing them 
Also, throwing them away would make replacing the old pref files into the library folder bit by bit pretty darn difficult!

Here’s to that sort of thing being the worst of our worries! No hard feelings. 
Best to you!
