The M.2 screw is fully lodged.
You're facing a tough situation with your B550M DS3H motherboard. It seems the screws holding the M.2 drive in place are extremely tight, likely due to the board's robust construction. Trying to force it might damage components or void warranties. Consider using a specialized screw removal tool or a small drill bit designed for such tight fits. If that doesn't work, consult a professional technician to avoid further risk.
Remove the stand, secure it with a vise or pliers, then carefully twist off the screw head. Be cautious while handling components inside the motherboard. If the screw is cross-threaded and difficult to remove, the screw may be damaged but the stand could still be usable if you obtain a new one. You might only need a replacement stand.
Pliers, proceed with caution. It seems the screw is stuck much more than it should be in the standoff.
