Quick answer
2005-0004 appears on Nintendo Switch when starting a game. Update the console; if it persists and you use a microSD card, try another card, format the original or remove it and download the game to system memory. If nothing works, it needs repair.
Safety first

- Turn the console off before removing or swapping the microSD card.
- Do not open the console or tamper with the card slot. If the error continues after Nintendo's steps, the repair belongs to Nintendo's service centre.

Safe checks you can perform
- Update the console
- Try a different microSD card

Update the console
- Who:
- you, with an internet connection.
- How:
- make sure the console has the latest system version and start the game that showed 2005-0004 again.
- Result that matters:
- seeing whether the game starts with the system up to date.
- If it starts:
- no need to touch the card.
- If the error continues and you use a microSD card:
- try another card.
- Evidence to keep:
- system version and name of the game that will not start.

Try a different microSD card
- Who:
- you, if you have another card at hand.
- How:
- turn the console off, swap the microSD card for a different one and download and start the game again.
- Result that matters:
- knowing whether the original card is what stops the download completing.
- If it works with the other card:
- the problem was the original card.
- If it does not work either:
- remove the card and try system memory.
- Evidence to keep:
- brand and capacity of each card and the result with each.

Format the original card
- Who:
- you, after backing up screenshots and videos to a computer.
- How:
- if you have no other card, or the second card worked and you want to use the first again, format it from System Settings > System (on Switch, under Formatting Options) and try again.
- Result that matters:
- seeing whether the original card works once formatted.
- If it works:
- the problem was the data on the card.
- If it still fails:
- download the game to system memory.
- Evidence to keep:
- date of the format and the result afterwards.
Formatting erases the whole card; back up screenshots and videos first.

What it means
Nintendo describes 2005-0004 as an error shown when starting a game on Nintendo Switch; the page is listed for Switch and Switch 2. After a system update, all its steps revolve around the microSD card: try another, format the problematic one or download the game to system memory. If the game works from system memory, you can play that way or use a different card. The code does not prove on its own that the console is faulty; Nintendo only asks for repair if the error persists.
