Something happened and your PIN isn’t available. Click to set up your pin again.

Firstly I am sure this problem has been addressed many times before, so my apologies in advance.
Win 11 Home Premium – Safe Mode

I recently acquired a Dell Vostro 15 3000 Core i5 10th Gen.
Prior to accessing the www for the first time I went to sys.config & clicked on safe mode.
After the standard re-start I had this message "Something happened and your PIN isn’t available. Click to set up your pin again."
However, after clicking the onscreen link nothing happened, this was repeated in a number of occasions with the same result.

I did a restart using F2 to get to the BIOS setup but was unsure of the options available to remedy the problem, has anyone had a similar
problem which they managed to resolve?

Any help would be appreciated.

Regards.
