corrupt emuNAND?

[SadChomper]

Hello, emuMMC on my modded picofly OLED was working fine until it suddenly crashed and won't boot past the nintendo switch logo anymore. OFW and sysMMC both boot fine however, its only the emuMMC. I tried fresh installs of atmosphere to no avail. I havent found a solution anywhere. I checked the error reports in the erpt_report folder, and I noticed each time i'd get stuck while booting it would generate multiple error files, the first generated file always contains error code 2162-0004, and the rest of the files all contain error 2155-8007.
Please help

Are you using ExFat or FAT32 for the SD card format? If it's exfat that's your problem. Reformat the SD card in FAT32 and relax your games.

"Error code 2155-8007 on a Nintendo Switch occurs when the console is unable to access an online feature. This can be caused by an issue with the network connection, the DNS, or the system itself."

2162.0004 looks like an error reading corrupt data.

On a separate note,I have over the last year and a half read about picofly modchips causing corrupt data. I wonder if it might be related to your problem here. It's good your sysnand /ofw works fine. Could your modchip have a loose connection somewhere ?Maybe the DAT0 emmc pressure fit adapter needs to be adjusted?
