`warnings.warn` function in the conventional `fit` method in `sklearn.cluster._spectral` raises a non-descriptive `TypeError`

### Describe the bug

I was emulating `GridSearch` methodology on fine-tuning `sklearn.cluster.SpectralClustering` with python `for` loops and encountered the error mentioned in the issue topic. This is weird because the error points to the call of `warnings.warn` from `cpython` (built-in). 

I tested the built-in function such that I run:
```python
warnings.warn(
    "The spectral clustering API has changed. ``fit``"
    "now constructs an affinity matrix from data. To use"
    " a custom affinity matrix, "
    "set ``affinity=precomputed``."
)
```
and it put out a warning conventionally acceptable. 

Hence, I have no idea why the error pointing to `warn` is raised instead of the warning itself or instead of the actual error while running the algorithm is traced and displayed. 

### Steps/Code to Reproduce

```python
from sklearn.cluster import SpectralClustering
from numpy import array

X = array([[ 1, 0, 1, 103, 1,   1,   1,   1, 1, 1, 1, 1, 9],
           [ 0, 0, 1,   1, 1,   1,   0,   0, 0, 1, 1, 1, 1],
           [ 1, 0, 1,   0, 1,   1, 478, 478, 0, 1, 1, 1, 1],
           [ 1, 0, 1,  30, 1,   1,   5,   5, 0, 1, 1, 1, 1],
           [ 0, 0, 1,   0, 1,   0,   1,   0, 1, 0, 4, 1, 1],
           [ 0, 0, 1,   1, 1,   0,   1,   0, 1, 0, 5, 1, 1],
           [ 0, 0, 1,   1, 1,   1,   0,   0, 0, 1, 1, 1, 1],
           [ 0, 0, 1,   5, 1,   1, 355, 177, 0, 1, 1, 1, 1],
           [ 0, 0, 1,   1, 1,   0,   1,   0, 1, 0, 6, 1, 1],
           [ 0, 0, 1,   1, 1,   0,   1,   1, 1, 0, 6, 6, 1],
           [ 0, 0, 1,   1, 1, 123,   1,   1, 1, 0, 2, 2, 1],
           [ 0, 0, 1,   1, 1,   1,   1,   1, 1, 1, 1, 1, 1],
           [ 0, 0, 1,   1, 1,   1,   0,   1, 0, 1, 1, 2, 1]],
          dtype=float)
    # sampled from actual dataset shaped `(2833, 532)`

clusterer = SpectralClustering(n_clusters=2,
                               eigen_solver='arpack',
                               random_state=42,
                               affinity='nearest_neighbors',
                               degree=2)

clusterer.fit(X)
```

Although the above reproducible codes involving `X.shape==(13, 13)`, the `.fit` sometimes works fine without encountering the error for extremely small varieties of sampling to `X.shape==(n_samples >= n_attributes, n_attributes)`.

### Expected Results

- A specific indication of the actual cause of the error is included in error traceback; or
- An alternative process was introduced in the module to work around the initial error.

COMMENT:
You mean that it fits without error, @Micky774 ?
Is it possible that the error itself related to `Cython`, since it was pointing to built-in function `issubclass`? How do I integrate `Cython` with `sklearn`?
