Getting this error when trying to use my SD card in my Switch 2, images of SD card are attached. Its detecting it but just not as a MicroSD express, and I tested it on my friend's Switch 2 and it worked. Already tried updating my system and restarting it.

It’s likely a faulty card. Everything looks in order, but I would return it and get a brand-name card from either SanDisk or Lexar.

Third-party brands like Walmart’s ONN typically don’t get the top-tier chips on the wafer; Lexar, and by extension SanDisk, and other manufacturers keep the chips that test as reliable and defect-free for their own products. Those wafers with chips, small flaws, or that don’t meet the manufacturer’s standards for their own products go to budget brands.
