ESP32 Marauder v4 OG/UPDATE ERROR - FAIL OPEN ROOT

[perseu-dv]

When I try to install firmware, I get an UPDATE ERROR message, then it returns to the launcher options and I get a FAIL OPEN ROOT message when I try to access SD, and it won't let me in.
Anyone else having the same problem? It happens to me with all firmware versions.

Usually it is SDCard related..

Can you format it in FAT32 using Rufus tool?
