I recently downloaded the Voukoder (v9.3) app and the VEGAS Pro 18-19 connector (v0.9.11). When I used it to render on Vegas Pro v19.0 build 341 initially, it popped up a dialog (alongside the VP render dialog) which showed details of the render process.

For some reason though, that dialog doesn't appear when I use it today. The VP render dialog is there, but it doesn't show everything, e.g., FPS, MB rendered, etc., which I noticed seemed normal when I was comparing it to the Voukoder render dialog when it was working.

I have uninstalled the app and connector, rebooted and reinstalled them twice now, but no change - and the files appear to be in the right place (i.e., C:\Program Files\VEGAS\VEGAS Pro 19.0\Voukoder-x64.fio2007-config and C:\Program Files\Voukoder\voukoder.dll).

Has anyone seen this before? Here are my system specs for reference:

Windows 10 Pro 21H1 build 19043.1165

64 GB RAM, 2 TB M.2 SSD media drive

RX 3060 XC GPU (12 GB RAM) with version 471.96 driver

...and the MediaInfo output from the Project Media:
