Hello @Flávio3055461806oc,
I'm sorry to hear about the issue you encountered with your Illustrator file. It seems that the sudden shutdown of your notebook might have caused the file to become corrupted. Unfortunately, once a file is corrupted & text import options dialog appears on opening a file, there is usually no way to recover its content.
To avoid similar situations in the future, I recommend saving your work regularly while working on it to prevent data loss in case of unexpected shutdowns or other issues.
If you have any other questions or need further assistance, feel free to reach out.
Best,
Anshul
