All Nexus simulators fail with “Provider platform was not found”

Hi, I have the following issue: both my own code and the official examples currently fail on all Nexus simulators with the same
“Provider platform was not found” error. No job is created or job ID returned.
For example, using nexus:H2-2E produces:

Traceback (most recent call last):

  Cell 

marimo://guppy_example.py#cell=cell-13

, line 8, in <module>

    job = qpu.run(qir_program, shots=shots.value)

          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File 

"/home/me/.cache/uv/environments-v2/guppy-example-94cfac2e227d3497/lib/python3.12/site-packages/aqora/qpu.py"

, line 126, in run

    encoded, serialization_format = formats.encode(sources, self.input_formats)

                                                            ^^^^^^^^^^^^^^^^^^

  File 

"/home/me/.cache/uv/environments-v2/guppy-example-94cfac2e227d3497/lib/python3.12/site-packages/aqora/qpu.py"

, line 87, in input_formats

    self._input_formats = self._load_input_formats()

                          ^^^^^^^^^^^^^^^^^^^^^^^^^^

  File 

"/home/me/.cache/uv/environments-v2/guppy-example-94cfac2e227d3497/lib/python3.12/site-packages/aqora/qpu.py"

, line 156, in _load_input_formats

    raise LookupError(f"Provider platform {self._platform!r} was not found")

LookupError: Provider platform 'nexus:H2-2E' was not found
Could you please check whether there is a service or access issue and advise how to resolve it?
Thank you!
