YubiKey two-factor authentication on Chrome & Edge doesn't seem to work

[tepperly]

My site is running WordPress version 5.9.1 and two-factor 0.7.1. My browser is Google Chrome Version 99.0.4844.51 (Official Build) (64-bit), and I also tried logging from Edge.
My WP user account is configured to use FIDO U2F Security Keys, but it doesn't work anymore. I type in my username/password, and the next screen tells me to insert my key and press the button. Normally another window appears, but it's not appearing. Pressing the button has no visible impact.
Doing Register New Key similarly doesn't bring up the extra window like other functioning FIDO U2F websites.

Thanks,
Tom
