Red Giant Universe Transitions Crashes Premiere

I know this is a very old post but I just ran into a very similar issue.  I was excited to try all of the fixes suggested but none worked for me (and we're obviously all on different versions of software).  We were struggling with Universe Transitions (Slide transition specifically).  The entire Premiere Pro project would come to a call and more often simply crash even when not rendering.  We're on Windows 10 Pro.

After troubleshooting an entire day, we found that it was the presets we made within the Universe Slide transitions user interface that were causing the problems.  We deleted the user presets folder (in Windows Explorer) and it ran perfectly (but of course, the transitions all defaulted to the default settings and we needed to redo each transition's properties).  We had a lot of them so we created another preset thinking the old presets were just corrupted. We chose that preset for a few transitions and tried to export- this crashed the system the moment it reached the transition.  Deleting the presets folder again (outside of Premiere Pro, in Explorer) we lost all of the transition settings but it again ran perfectly.  We can manually change the settings of the transition but the moment we create and use a user preset (a preset within the Universe Transition panel), it kills the system.  We've done reinstalls and uninstalls and we just can't use created user presets...  Not sure who's at fault (if it's Adobe or Maxon) but at least this "work-around" works perfectly for us.  Maybe it'll help someone else out.

As the problem is related to Universe only, I think you'll get better answers by calling redgiant's support
