Problem loading songs after OSX Catalina update (some plugins won't load?)

I’ve updated to the latest macOS 10.15.2 (Catalina) and when I try to open any of my songs with audio plug-ins in them, Renoise gets stuck while trying to load the XRNS. Works fine with XRNS based on samples only. Any suggestions appreciated, thanks!

I just removed a plug-in by TAL, the “elek7tro-II” and certain XRNS files load up again!
