Source.Python fully loads, but segfaults immediately on loading my plugin.\n\nLooks like the plugin interrogating the STV user is breaking something, similar to the condition crashing Sourcemod (https://github.com/alliedmodders/sourcemod/issues/2264). Running under gdb, I get this stack trace (truncated the Python calls):\n\n\u003cdetails\u003e\n\u003csummary\u003eGDB stack trace\u003c/summary\u003e\n\n```\n#0  0xf62d73aa in
