Hello,
So, a core dump means you had an abend. Besides the core dump, was there any higher-level messages (e.g. Python stack trace or OpenGL error messages)? If not, even a core dump can provide some insight to what went wrong depending on where exactly the crash ensued.
Can you identify which executable crashed? Depending on the answer, it’ll be easy or difficult to analyze the dump. For example, if the crash occured inside python or libvtkCommonCore-9.1.dll you can get debug versions of these with relative ease. If the crash took place inside one of the OpenGL backend libraries, you can have a hard time getting the debug version of them because they are supplied by your graphics card vendor.
Once you have the debug version of the binary that crashed, you can analyze the core dump with gdb: linux - How do I analyze a program's core dump file with GDB when it has command-line parameters? - Stack Overflow
