Error when switching from subtitling to other project

I get an "Object reference not set to ..." error if I do the following:

Open a vtt file with subtitling preview for translation.
Close the file.
Switch to another project.
Open a (non-subtitling) file for translation. This is when the error pops up.

I tried a few things like pinning/unpinning the subtitling preview window (It's on a second screen, outside the main Studio window), closing it before closing the vtt file, but it does not solve the problem. Restarting Studio clears it.

Hello ,

I have tried to reproduce this now on two separate W10 machines and are unable to do so.

Maybe try re-setting windows layout in Studio to see if the problem still occurs.
