pcie nvme drive is set readonly/write protected. i've been using the drive six months to a year and now i can't even format the drive. no changes have been made in the past 3 months (Shy windows 10 updates)

disk partition shows as:

Current Read-only State : Yes

Read-only  : No

Boot Disk  : No

Pagefile Disk  : No

Hibernation File Disk  : No

Crashdump Disk  : No

Clustered Disk  : No

admin supposedly has read/write according to windows (so running something as admin; i still get write protection can't save files to the disk)

i've tried setting permissions; and using diskpart to clear the read only flag. Then I tried copying the files off to another drive and formatting (Couldn't get the files to copy.)

Then I tried formatting (can't- disk is write protected.)

not sure what to try next. any suggestions?
