Hey, I'm getting the following error when trying to create a Dynamic Provider in pulumi (using 
pulumi up
): 
Diagnostics:
  pulumi:pulumi:Stack (<my-stack>):
    /Users/<my-path>/venv/lib/python3.10/site-packages/grpc/_server.py:456: RuntimeWarning: coroutine 'invoke.<locals>.do_rpc' was never awaited
      return None, False
    RuntimeWarning: Enable tracemalloc to get the object allocation traceback

  pulumi-python:dynamic:Resource (foo):
    error: Exception calling application: There is no current event loop in thread 'ThreadPoolExecutor-0_0'.
and I had no issues with my stack before adding my Dynamic Provider. I've tried with multiple providers but not even the simple 
Random
example from the documentation
Dynamic provider code: 
import binascii
import os
from typing import Optional

from pulumi import ResourceOptions
from pulumi.dynamic import CreateResult, Resource, ResourceProvider


class RandomProvider(ResourceProvider):
    def create(self, inputs):
        return CreateResult(id_=binascii.b2a_hex(os.urandom(16)), outs={})


class Random(Resource):
    def __init__(self, name: str, opts: Optional[ResourceOptions] = None):
        super().__init__(RandomProvider(), name, {}, opts)


my_resource = Random("foo")

wheel                     0.37.1
I've also tried it in a fresh python 3.9.14 environment with the same result. And I tried this: https://github.com/grpc/grpc/issues/29262#issuecomment-1142667300 without any luck
So this appeared to be a problem with using DynamicProvider outside the 
__main__.py
file. https://github.com/pulumi/pulumi/issues/7453

i'm not sure that issue applies in this scenario. I am able to use a DynamicProvider outside of main, but I do get the same error you are seeing whenever I use an async api call within create method
class ManagedVNetProvider(ResourceProvider):
    def create(self, props):
        client_config = pulumi_azure_native.authorization.get_client_config()
due to the 
get_client_config()
call i see the exact error as you. when i take it out, the resource provider works fine
