How to fix NVMe SSD Locked in Read-Only Mode

Error code: NVME_READ_ONLY

What this error means

The solid state drive controller detects media wear or flash array errors and locks itself in read-only write-protection to prevent further data loss. The user can read files but cannot save, modify, or format the drive. Another common trigger is excessive bad blocks.
