I've been using the new text panel to transcribe some source clips and it was stuck on one clip, so I left that sequence to work on another one while it did its thing. I reopened the text panel to this error message.
I restarted the text panel, then restarted Premiere, then restarted the computer, none of which worked. I opened the project on another system using the Productions project and the error persisted on their system as well. All of my previously transcribed clips were also affected and now the text panel doesn't work at all in this project. I brought the affected clip into a new project outside of the Production and the text panel recognised it, but trying to retranscribe it ends with the same error. There's nothing weird or corrupt about the clip itself. It plays and interacts with the NLE as normal. At an hour and 46 minutes long, it's on the longer side, but we have clips as long in the original project that Premiere had no problems with. It's a simple Q&A interview with one interviewer and one subject, so there's no action or multiple speakers to muddle the AI.
I haven't been able to replicate the issue with other clips, so I'm assuming it's a fluke, but I would love to know how to fix it so I don't have to trash an entire project that editors are working out of and relying on the script sync in the text panel.
