I don't know about the popup; realize that we have gone through so many hundreds of K of changes running the hybrid mode and now dip3 mode, its hard to say; note that there is even a different case that your wallet is going to go through when we enable chainlocks in a few days (two more DIPS actually get set in mainnet soon), so what Im saying is we will be running the pure voting DM mode in a few days, and now the error can be streamlined.

In any case, I just modified the error message to ask the user to unlock the wallet if its locked.
