Ethereum client Prysm: Identified the system issue and provided a temporary solution

The Ethereum client Prysm has indicated that it has identified the issue and provided a quick temporary solution. All nodes should disable the unnecessary generation of old states in Prysm to handle expired proofs. Simply add the flag "--disable-last-epoch-targets" in the beacon node. This parameter is applicable to version v7.0, so there is no need to further upgrade the beacon node; just add this parameter. The validator client does not require any changes.
