SN550 nVME 1TB Stuck in ReadOnly

I recently bought an SN550 and IT has been running smoothly until suddenly it got stuck in readonly mode.

Cannot boot Windows, i get the recovery tool but nothing works since drive is in readonly.

Tried with Diskpart, I can remove readonly flag, but cannot chance current mode: readonly.

I tried with the registry trick. But still have current mode: readonly.

I tried with ChkDsk, same result.

Amy ideas? Is my drive bricked?

Secure your important data from the drive as quickly as possible!

Read-out the SMART data of your drive.
It might be failing in which case it can switch to read-only mode in order to control damage.
