Endless loop of Yubikey auth with Chrome extension - cannot disable Yubikey under LastPass Free

[Michael12345]

I enabled Yubikey during a LastPass premium trial that has now ended. Today when starting Chrome, I am prompted for Yubikey authentication. If I push the button, I just get re-prompted for the Yubikey repeatedly.

I thought I could temporarily disable the Yubikey and continue with it, but under LastPass free, when I go into My Vault > Account Settings > Multifactor Options and try to edit my Yubikey settings, I get an "It's time to upgrade!" message.

Any suggestions?

I also find it interesting that I can access my vault using my just my master password, and Chrome auto-fills seem to be working fine even though the LastPass Chrome extension seems to be rejecting my Yubikey authentication.
