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.
