Official Solution
This error code may indicate an issue with the data on your microSD card.
Nintendo suggests checking the software for corrupt data. If the issue is not resolved, formatting the microSD card may help. If the error persists with multiple cards or after formatting, there may be an issue with the console or the microSD card itself.
Common Symptoms
- The error appears when launching a game or application that is installed on the microSD card.
- The software takes a long time to load and then crashes with error 2002-4373.
- The issue occurs after a game update has been downloaded to the SD card.
- The Nintendo Switch console may freeze or become unresponsive when this error occurs.
Hardware Information
This error points directly to a problem with the microSD card's integrity. It can be caused by a low-quality or counterfeit card that cannot handle the read/write speeds, or a legitimate card that has developed bad sectors over time. It is very rarely an issue with the Switch's card reader.

BeginnerStep-by-Step Solutions
Formatting the microSD card will erase all software data, but your save data (stored on the console's internal memory) will not be affected. You will need to redownload your games.
Check for Corrupt Data
Go to System Settings > Data Management > Manage Software. Select the problematic game, then choose 'Check for Corrupt Data'. The system will attempt to find and redownload any bad files.
Archive and Redownload the Game
From the same 'Manage Software' menu, select 'Archive Software'. This deletes the game data but keeps your icon and save data. Then, select the game icon on the HOME Menu to redownload it.
Move Data Between System and SD Card
Go to System Settings > Data Management > Move Data Between System / microSD Card. Try moving the problematic game from the microSD card to the system memory. If it launches correctly from system memory, the issue is with the card.
Format the microSD Card
Back up any screenshots to a PC if needed. Go to System Settings > System > Formatting Options > Format microSD Card. Follow the prompts to completely erase and reformat the card for use with the Switch.
