EvmKeyAssociateRateLimitExceeded

associate_evm_key was called again before the per-UID rate limit since the last association elapsed. Compare blocks since the association recorded in the AssociatedEvmAddress storage against the EvmKeyAssociateRateLimit runtime constant and retry later.

Declared by the SubtensorModule pallet; it classifies to the semantic code rate_limited.

Remediation

Wait for the rate-limit window to pass, then retry
