Hi Claire,
I cannot reproduce the error with the docker image: ghcr.io/fenics/dolfinx/dolfinx:v0.8.0 .
It seems lie you are using conda for your your installation. Do you mind sharing how you set up your environment?
(This error looks similar to: Problem reading mesh checkpoints (N-to-M) with adios4dolfinx - #7 by Exon)
