Well..could you provide us with elaborate information regarding your current switch hacking problems that you're facing.
Likewise could you provide us with more details please?
What happened that lead to this.
Were you installing games to your switch when this happened.
Is your SD card formatted to exFAT or FAT 32 perhaps?
Cloud icon can appear due to a myraid of problems, to name a few: corrupted data, signature patches are missing, SD card got corrupted, bad dumps of NSPs/XCIs etc
If you're using atmosphere by any chance then get the signature from here here
Format your SD card with guiformat to FAT32+32K cluster size to prevent further DATA corruption that could result thereof.
GUIformat - get it from the link below
Make sure to backup everything beforehand! Otherwise you'll lose all of your data.
For installing NSPs I'd recommend you Goldleaf
Make sure to place the NRO in SD:/switch/
