Unable to Log Into Riot Client Despite Correct Credentials

For the past two days, I have been unable to log into the Riot Client despite entering the correct username and password. When I tried logging in via Google, it worked, but logging in directly through the Riot Client consistently fails. I also attempted using the QR code login feature, but that didn’t resolve the issue either.

I submitted a support request, but there has been no resolution or helpful feedback. This is incredibly frustrating, as I am unable to access my account properly. I expect Riot Games to address this issue promptly and provide a clear solution so I can use the platform without further interruptions. Please assist as soon as possible!
