A new system update for the Nintendo Switch 2 is causing serious issues for some players—and it could affect your game library.

According to multiple reports, firmware version 22.0.0 is breaking compatibility with certain microSD Express cards, making stored games completely inaccessible. For many users, this means losing access to a large portion of their installed titles overnight.

With storage already limited on the console, the situation is quickly becoming a major concern.

microSD Express Cards Suddenly Stop Working

Over the past few hours, numerous players have taken to forums like Reddit to report the same issue:

After installing update 22.0.0, their microSD Express card:

• Cannot be read by the system
• Is flagged as incompatible
• Still shows screenshots, videos, and save data
• But fails to launch installed games

In short, the storage device partially works—but not for the one thing it’s mainly used for: playing games.

1TB Cards Appear to Be the Most Affected

Early reports suggest that certain models are hit harder than others.

In particular, PNY 1TB microSD Express cards seem to be the most commonly affected.

That’s a big problem considering these cards are not cheap. A 1TB microSD Express card can cost around $150, making this more than just a minor inconvenience—it’s a costly issue for affected users.

Even worse, simple fixes like restarting the console do not resolve the problem.

Storage Is Already a Major Limitation on Switch 2

The bug is especially frustrating because external storage is almost essential on the Switch 2.

The console includes a 256GB internal SSD, which is a big improvement over the original Switch—but still not enough for modern games.

For example:

• Final Fantasy VII Remake can take up to 90GB alone

That means just a few large titles can completely fill the internal storage, forcing players to rely on microSD Express cards.

Ironically, Recent Updates Were Actually Good

What makes this situation worse is that recent updates had been well received.

Firmware 20.1.5 introduced several useful improvements, including:

• Enhanced graphics for older Switch games in handheld mode (up to 1080p)
• Improvements to GameChat
• New private notes in the friends list

On paper, Nintendo was delivering meaningful upgrades.

But update 22.0.0 has overshadowed those improvements with a critical storage issue.

No Official Response From Nintendo (Yet)

So far, Nintendo has not issued any official statement or fix.

There’s:

• No patch
• No acknowledgment
• No timeline for resolution

For now, affected players are left with only one workaround:

👉 Transfer games back to the internal storage

But this is far from ideal—especially for users with large game libraries that exceed the 256GB limit.

What You Should Do Right Now

Until Nintendo releases a fix, the safest approach is simple:

👉 Avoid installing update 22.0.0 if you haven’t already

This is particularly important if you own:

• A 1TB microSD Express card
• Especially from PNY

If you’ve already updated:

• Keep an eye out for future patches
• Avoid formatting your card unless absolutely necessary
• Backup your data if possible

A Bigger Problem for Switch 2’s Ecosystem

The Nintendo Switch 2 relies heavily on its expanded game library and backward compatibility.

With hundreds of compatible titles—and new releases arriving regularly—storage quickly becomes a bottleneck.

Issues like this highlight how critical external storage is to the overall experience.

Conclusion

Update 22.0.0 was supposed to improve the Switch 2 experience—but for many players, it has done the opposite.

By breaking compatibility with microSD Express cards, it directly impacts access to games—arguably the most important function of the console.

Until Nintendo responds with a fix, caution is the best approach.

Because right now, installing this update could mean locking yourself out of your own game library.
