Does a once rebooted PiOS nowadays have MBR or GPT?
If MBR, some failure in fstrim or queuing or block handling or a simple zeroing of just the first sector can make the SD-card look blank.
If GPT, there is a backup at the end of the SD-card so at least CLI tool gdisk can fix it then usually.
Also a standard RPiOS created image has 2 partitions at known locations, one could create an new RPiOS default partition table.
Then you could do:
sudo fsck /dev/sdX2
and/or
sudo lsblk -f
to see if whole card is trimmed/wiped/corrupted or just blocks at the beginning.
