Thanks friend! Your script helped me a lot ...
The truth was I had days trying to solve somehow being able to play Minecraft on my Mac with Monterey with this error.
Justo had little more than 3 weeks without being able to play. I thank you a lot.

Thanks!

Thank you. I solved the crash problem that occurs in mac os 12.1 month through this script.

You are the best. Thank you very much! Solved the issue
