hello，everyone!
when I run snap.pp.filter_cells(adi_adatas, min_tsse=7,n_jobs=1)
It always makes the following error,,how can I solve it? thanyou very much

Reproduce the failure with snap.pp.filter_cells(adi_adatas, min_tsse=7, n_jobs=1). Start by reading snapatac2/_utils.py at line 30 and the reported pyanndata anndata.rs location, then trace the dimension mismatch during worker reads. Done means the filtering operation completes without a pyo3_runtime.PanicException and preserves valid dimensions.
