‘Failed to create a login nonce’ message

Hi there, today, out of the blue, my site with Two-Factor 0.7.3 installed started to display the “Failed to create a login nonce” notification. I’m running WP 6.1.1 and it seems to me the latest WP upgrade (6.1 => 6.1.1) might have caused this, as I made no changes to the config myself.

I disabled the plugin by renaming its folder, but in this case, I can’t log in either. The login screen just keeps refreshing and gets back to the credentials screen. Is there a way to disable the plugin and get to the WP admin screen?

BTW – I have no cache plugin and clearing just the browser cache doesn’t work…
