To answer the Clarification Tag.
1 password can't fill in the fields at times.
When this happens I still see the popup like seen in the screenshot above, but I can click it as much as I like, it doesn't fill in the Username or password.
I also cant fill in the password using ⌘ + \ or the the Orion extension (where I also see the website, and can click autofill, but it doesn't do anything)
This is resolved by quitting the browser and then going to the website again.
I am not sure how I get into the state, but I think it happens when I leave my laptop plugged in and unlocked until it auto lock and tunrs the screen off.
I am on an M4 Macbook Pro
I hope this clarifies this more.
