[Bug] TypeError("'None Type' object does not support item assignment")

[scorwin]

Steps to reproduce

1. (How do you make the issue happen? Does it happen every time you try it?)

Using WhisperX with the large-v2 model, float16, and batch size 8 (all chosen for me by the software), I attempted to generate a VTT file of subtitles from an English-language .avi file.

3. (Make sure to go into as much detail as needed to reproduce the issue.)
4. (If there are any files, like any strings.xml, don't forget to include them.)

Expected behaviour

Perfection. Well, okay: a VTT output file.

(What did you expect to happen?)

Actual behaviour

After a few minutes, I got the error message in the title. There was no other output.

(What happened instead? How is it different from what you expected?)
