I haven't seen this particular error happening, is this still an issue?

It doesn't seem to happen now, but corpus is not being updated for some reason since December https://github.com/filecoin-project/ref-fvm-fuzz-corpora/tree/master

Resolved by repairing the access token for https://github.com/filecoin-project/ref-fvm-fuzz-corpora
The unreproducible crash resolved itself.
