Unable to sign in with 2FA (Steam deck / Arch)

[Laqota]

When trying to sign in with 2FA on such as a phone authenticator or email a blank white box will appear (which I'm guessing in the authentication page)

I had to create a new account to get it working until this is fixed.

I'm on a Steam deck which uses Steam OS (which is based on arch Linux)

So far, i've never been able to login through the app itself, it's a bug with WebView2 and Wine that turns that window white. A workaround is to login into Roblox on the browser, click to join any game and leave, the account should be logged in into the app by this point and you can open the app normally.
