SUMMARY
I'm observing this behavior on a new installation of KDE/KMail on Arch Linux.
When trying to add a new Gmail account, Kmail (correctly) opens a browser to
complete the XOAUTH/OAuth2 process necessary for Gmail. However, there is some
sort of error in the URL and/or the request, and Gmail will present an error
(see attachments for screenshots of the errors). This does not affect
previously-configured Gmail accounts; I have another Arch Linux system (running
Plasma 6 but upgraded from Plasma 5) with an existing Gmail account that
continues to work without any issues.

To try to eliminate potential browser-related issues (I'm using Firefox 130),
I've disabled all relevant/pertinent add-ons. I've tried logging into my Gmail
account first so that the new tabs opened by KMail would already have the
necessary credentials (it didn't help). I've also made sure that I'm completely
logged out (logged out, closed all windows, restarted Firefox) to see if that
would help (it did not). Based on the wording in the error messages, I suspect
(but cannot verify) that this may be due to a recent change in Google
authentication URLs or APIs.

STEPS TO REPRODUCE
1. Use the Add Account Wizard to attempt to add a new Gmail account.
2. When the browser opens, it will report an error (see attachments). It may
also open an additional window or tab with more information about an invalid
OAuth2 scope name.

OBSERVED RESULT
Google reports an error and does not authorize KMail to access Google
resources.

EXPECTED RESULT
The authentication process would proceed as expected and allow the user to
authorize KMail to access Google resources.

SOFTWARE/OS VERSIONS
Windows: N/A
macOS: N/A
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: Arch Linux kernel 6.17.0-arch1-1
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
I have tried some (very minor) troubleshooting by comparing the working KMail
installation on a second system with the new KMail installation that isn't
working. The working system previously ran Plasma 5 and still has some
Qt5-related packages installed; installing those on the new system did not
help. Later today I'll install a secondary browser to verify that this isn't a
Firefox-related failure, although that seems unlikely.
