When Launching Pro Tools, there is an error from PACE (PACEEdenExperienceProxy):
This Application has failed to start because it could not find or load the Qt platform plugin "windows" in "",
The PACE service is running. iLok itself runs and logs in. I've uninstalled everything since the issue started occurring, though I cannot map it to any system change. I've uninstalled and reinstalled PACE/iLok (latest).. I've completely uninstalled Pro Tools and reinstalled it (latest). I've removed any environment variables containing the QT5 dlls. I've read about Slate interfering. That's gone now as well. I'm not going to roll back my machine over this.
This issue is encountered on other software packages but here with PACE, it's relentless. Anything I can search for on this issue, whether related to this software or others, does not work. Opening a ticket with them as well.
