Cannot write it's stuck in read only

My new sandisk ultra USB 2.0 is write protected.
I tried to change it through command prompt ( attributes disk clean read only) but the issue is not solved

I tried to change it through regedit. But still issue is not solved.

I tried to change it through third party software. But it didn’t work.

Whatever I do, I can disable readonly but could not change Current read-only state to No.

Any help guys? What to do?
