SIGSEGV in g_type_check_instance_is_fundamentally_a+0x11

OS: Ubuntu 24.04.1 LTS
GNOME: 46.0

I am running the SwingSet3 application (GitHub - thisMagpie/SwingSet3) with Orca enabled. The application crashes unexpectedly after about 10 minutes of interacting in different scenarios. I encounter a similar error when running IntelliJ IDEA with Orca enabled, but in this case, the error occurs almost immediately without any interaction required.

Could you please advise what might be causing this error and suggest any additional steps I could take to investigate this issue further?

This looks like an error in the bindings: something is holding a reference on the Java side to an object that was released on the C side. I recommend asking the application developers.

It would be useful to install the packages for the debugging symbols of libatk-bridge-2.0 and libglib-2.0
