open telemetry version - 0.44b0 python - 3.10 docker versions - ubuntu 20.04 running in Kubernetes cluster, on prem servers

The issue isn't reproduced systematically
many times i get the following exception (everything is fine except for the error printed)

Failed to detach context
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/opentelemetry/trace/__init__.py", line 573, in use_span
    yield span

    yield from invoker(request_or_iterator, metadata)
GeneratorExit

During handling of the above exception, another exception occurred:
Traceback (most recent call last):

there are related bugs but not regarding grpc instrumentation https://github.com/open-telemetry/opentelemetry-python-contrib/issues/904 https://github.com/open-telemetry/opentelemetry-python/issues/2606

Also running into this same issue.

If I comment out my GrpcInstrumentorClient().instrument(), then the errors go away (same stack trace as seen above^). It is also non-deterministic for me unfortunately
