Read only mmc - radxazero - 16gb-4gb

so, i have 5 v1.51 zero boards and 2 v1.14, but today i faced up a problem while i was writing ubuntu in one of the boards.

The problem is that, i can write the img with no problem using “sudo dd if=imgfile.img of=/dev/sdb bs=1M” but when it boots i can’t even do a simple mkdir command because i receive a read-only message,

anyone here knows how to solve it ??

sometimes i can’t even boot, here there is video showing the errors
