Error in action with 2 VOSK libraries

SUMMARY
When I run any VOSK library regardless of size, the Speech Recognition engine runs for a few seconds then says "Subtitles Imported" in the edit subtitles popout as if it worked properly, but at the bottom right of the Timeline a red error message appears. The "SRT" it points to in the error is always different and never exists (Though I have caught a .WAV file by that name briefly existing at that path).

I've tried with various combinations of the tracks locked/unlocked, I've tried with various combinations of the tracks active/inactive. I've even tried making a brand new project with only that audio track in it. I've uninstalled/reinstalled VOSK, updated PYTHON, PIP, SRT, and KDEN. Installed VOSK and SRT directly in Python via Conda Prompt. I've done the default and custom folders as install paths. And of course I've checked around to see if anyone else has had this issue.

STEPS TO REPRODUCE
1. Install VOSK
2. Import Audio clip
3. Run Speech Recognition

OBSERVED RESULT
No subtitles generated, "Subtitles Imported" message in subtitling menu, error message at bottom right

EXPECTED RESULT
Speech analyzed and subtitles generated to audio track
