You can try these steps :
Launch Secure Folder and incorrectly enter the pattern or the PIN code. Forgot pattern or Forgot PIN code will appear at the bottom of the screen.
Tap on Forgot pattern or Forgot PIN code > Reset. You will be redirected to sign into your Samsung Account.
if this can be done you need to raise error report through the Samsung member
