Hi @JoySorrow,
Thank you for sharing the details about the cursor and selection issues in Illustrator 29.7.1. To help us investigate, could you let me know your OS and whether this happens with all files or just specific ones? A screenshot or short screen recording showing the cursor mismatch or selection glitch would also be really helpful.
In the meantime, you can try resetting Illustrator preferences after backing them up. If the issue continues, please test Illustrator in Safe Mode to see if the problem still occurs. You can follow these guides for reference:

macOS: https://adobe.ly/47AsTME
Once you've tried these steps, please let me know if the issues persist, so I can check further with the team.
Looking forward to your update,
Abhishek
