Unable to label more than four regions in Audio
I am running into a strange issue with an audio transcription task I'm trying to complete. I am able to label four regions of my file without any issue, but as soon as I attempt to label a fifth I get an error and the following stack trace:

I noted a user in the Slack support channel experiencing a nearly identical problem with a video task (4 labels are fine, the fifth throws this error) so perhaps it's reproducible in other task types too: Slack Support Thread
labeling configuration:
<View>
<Audio name="audio" value="$audio"/>
<Labels name="label" toName="audio">
<Label value="Speaker 1" background="#f500ff"/>
<Label value="Speaker 2" background="#ff0300"/>
</Labels>
<TextArea name="Transcript" toName="audio" perRegion="true" showSubmitButton="true" maxSubmissions="1" editable="true" required="true"/>
</View>
To Reproduce Steps to reproduce the behavior:
- Create new project
- Use MP3 file and "perRegion" TextArea (my view code is above)
- Label four regions in the file and enter transcripts
- Label a fifth region and attempt to enter a transcript
- The error will occur before even submitting the new annotation, seemingly as the app attempts to process text from the fifth transcript
Expected behavior More than four annotations on an audio file would work
Environment (please complete the following information):
- Label Studio Version 1.12.1
- Installed via PiP on Debian Linux 12.6 (fully updated), also tried the official Docker image
