Hi @Vlad,
To reproduce, first install iCloud add-ons from Chrome Store. Then, use it on for example orionfeedback.org. Click on sign up, then place the cursor on the new password field. iCloud will pop up with the crash image shown on the new password field. This option should open Safari when pressed to generate a new password from iCloud.
Next, for "Verification code for "$1," use iCloud to submit the 2FA code. For example, I use Reddit for login. After submitting the password, proceed with the 2-step verification. "Verification code for "$1" should be "Verification code for reddit.com." Note: I have already set up two-step verification on my iCloud password for Reddit.
