thunderbird - yahoo issue

Hey fellas!

If any of you is using Thunderbird (email client) are you able to access your yahoo emails? Because, for me, there's been an issue with this for the last week...

This is the error I'm getting every 10-20 seconds and it's becoming annoying already...



And yes, I did check the IMAP settings, but I'm not seeing anything wrong with them, they're the same as they've been when I first added this email account to Thunderbird and I've never had any issues with this until a week or so ago...

Also, I've no idea which cookies (and in which browser) this popup window wants me to enable because I'm only using Brave browser, I'm not using Firefox, so this shouldn't be an issue either since - like I said - I've been using TB for over an year without issues. So yeah... not sure what to do about this as only my yahoo email isn't accessible anymore, everything else works properly...

Does someone know how to fix this?

I've still not found out why this error happens, but I re-installed my OS anyway, and now it works (although I still get this popup window for yahoo...)

Just wanted to make this update...
