If the coin is POW it may only require some hashing power to get the blockchain moving again. We suggest reaching out to the mining pools and asking for assistance to help your community proceed with the swap.
If your coin is full POS only and the blockchain has stopped the only way to move the chain again is to update the communities wallets and revert back to POW/POS and jumpstart the chain with miners hashing power to have the ability to swap. This is an extensive, complex and time consuming task. It is unlikely that the Merge team will have the ability to assist in this process. We suggest reaching out to your coins community or the Merge community to seek and ask for assistance from the many unknown talented individuals amongst them.
