i have the same problem… i don´t know if there is any way to get back my OP to my wallet. I have seen some responses in similar topics but with different Vaults, and i think we have to find a exchange that could swap vAMMV2-RED/OP into OP again.
If i can find it i will come to inform here.
I had the same issue and was finally able to convert vAMMV2-RED to REDKoin then to OP on the Velodrome Finance site within Coinbase Wallet.
Go to “Browser” on Coinbase Wallet and enter app.velodrome.finance into the address bar. Navigate to the Dashboard and withdraw your available vAMMV2-RED. It should convert it to RED (REDKoin) - that’s what mine did.
Then on the app.velodrome.finance site, navigate to Swap. You should see your RED available to swap for OP. Then complete the swap and it should be converted back into OP.
