How it manifests itself: when making changes to the script, a saving error may occur. Settings that can cause an error when changed:
switching from audio recordings to synthesis (from synthesis to audio recordings)
change voice acting
change Active Listening settings
change the Interruption setting (enable/disable, add new words)
actions with audio recordings in the script
Temporary solution: if you urgently need to save the script, you can change its name and save it. Add or remove a symbol in the name, add or rewrite the name, etc.
