If you’ve been experiencing Steam Deck error messages, there are several things that you can do to fix the problem. These include allowing rootfs read-write access, installing system packages, and enabling keyrings. However, these methods have the potential to cause data loss on your SD card. To prevent this, you can try ejecting your SD card properly.
First, make sure that your SD card has enough space. Your SD card must be at least 32GB to work with the Steam Deck. You can also use a microSD card for expanded storage. Remember, however, that not all SD cards are compatible with Steam Deck. Also, be sure that the SD card has a high speed because this can help your Steam Deck load faster.
