The “PAYDAY 2 Switch NSP Update” is a ghost hunt. There is no magical patch that fixes the game. If you have a modded Switch, install the 1.4.2 update for stability, but accept that the game is a time capsule from 2018. Play the PC version via Steam Deck or your laptop—the heists are waiting there.
Do not go online (Nintendo Servers) with a modified NSP installed. If you connect to a heist with a modded update that unlocks paid DLC for free, your console will get a CDN ban. Use 90DNS or Incognito to block Nintendo’s telemetry. PAYDAY 2 Switch NSP UPDATE
