How do I fix 'asyncio.run() cannot be called from a running event loop'?
Fix
You're already inside an event loop (Jupyter, IPython, FastAPI handlers, async frameworks). Inside async code, just await the coroutine instead of calling asyncio.run(). In a notebook, use top-level await (result = await main()). From sync code running inside a loop's thread, schedule with asyncio.run_coroutine_threadsafe(coro, loop) or move the work to async. nest_asyncio is a last-resort patch, not a fix.
