st.io.read_h5ad doesn't work on a previously saved file using st.io.write_h5ad

[mejasmi]

I am using Stereopy 1.6.1. After performing clustering, I save the data using st.io.write_h5ad function.
I wanted to read from it later using the st.io.read_h5ad function.
But this is the error message if flavor='scanpy' :
Above error raised while reading key '/cells' of type <class 'h5py._hl.group.Group'> from /.

If I set flavor = 'stereopy' the function executes for a while, then provides this error message:

I even tried using scanpy to read the saved h5ad, but got the same error as the first one.

Currently the Stereopy tool is unusable.

not sure how to save to stereopy style.

currently I am save to scanpy style:
