I'm trying to run your script on Ubuntu 24.04 but when I do the script crashes with the following output:

gbopyrator --dump-save out.sav

Hey! You can try this tutorial, you're having permission issues:

https://support.epilogue.co/hc/en-us/articles/4403827118738-How-can-I-connect-my-Operator-device-on-Linux-under-a-non-root-user

Or you can quickly run chmod 777 the device in the /dev folder, it might be something like ttyS0 or ttyACM0 or some other value. But the safest way is by following the tutorial.
