Premiere Pro CS6: Export media window not opening when plugin is loaded

[MarioFinale]

In Adobe Premiere Pro CS6, the Export Media window does not open when "dfscPremiereOut.prm" is present in the plug-ins folder. Removing the "dfscPremiereOut.prm" and restarting Premiere Pro file allows the Export Media window to open normally. Yes, the timeline is selected for the Export Media window to appear.

There are no error messages; the window simply does not open. The plugin worked for the first export using frameserver, but failed to open the export window on subsequent attempts. Re-installed frameserver, uninstalled and reinstalled too. Restarted Premiere Pro and the computer multiple times but the problem persist. Also tried with several different projects, same issue.

After extensive research, a solution from 2012 on GitHub (specifically, this comment) proved effective. The issue arises when DebugMode frameserver is the last preset used for export (indicated in the project file as <MZ.Prefs.Export.LastExportedPreset>), causing the window to fail to open on subsequent tries. To circumvent this, you need to avoid saving after using the frameserver for export, or alternatively, export a brief segment of the video (even just one frame) in any format other than DebugMode Frameserver before saving. Another way to avoid this issue is to close the project, open the *.prproj file with a text editor and delete the contents inside the <MZ.Prefs.Export.LastExportedPreset> tag, saving and then reopening the project

This workaround is quite sketchy...
