Works for me with a default cube with skin+subdiv. No crash.
Do you have a .blend?

Hi, thanks for reporting. I can confirm in 3.3 (04a75c90d58ab393db5ce7d37f29655caa82097d)
Calling it a Regression as crash does not happen in 3.1. Will bisect.

index is 0 at the first assertion here:

BLI_INLINE BMEdge *BM_edge_at_index(BMesh *bm, const int index)
{
 BLI_assert((index >= 0) && (index < bm->totedge));
  BLI_assert((bm->elem_table_dirty & BM_EDGE) == 0);
  return bm->etable[index];
}
