Hello,
Thank you for posting in Q&A forum.
When you create a new Passkey using the Chrome browser, you may be asked to enter your Windows Hello PIN twice for security reasons to ensure that the operation is performed by you. This two-factor verification is done to prevent unauthorized access and ensure that only you can create a Passkey.
Normally, entering your PIN twice when creating a Passkey is not part of the standard process, but in some cases, it may be an extra step for added security. Chrome browser may use this method to increase security when creating a Passkey.
Some users have the same question as you, you can try turning off the "Use Windows Hello when filling in passwords" option through the Chrome browser to see if it helps.

I hope the information above is helpful.
Best Regards,
