I keep getting this same error
Client Version: 2023.7.1
com.faforever.client.login.TokenRetrievalException: {"error":"invalid_grant","error_description":"The provided authorization grant (e.g., authorization code, resource owner credentials) or refresh token is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.

You can try with the latest FAF production release:
https://github.com/FAForever/downlords-faf-client/releases/download/v2023.8.0/faf_windows-x64_2023_8_0.exe
If it does not work, for whatever reason - try the alpha client, which is in public testing phase right now to mitigate the DDOS. It has some bugs, like non-working country flags, but at least you should be able to login and play online again.
https://github.com/FAForever/downlords-faf-client/releases/download/v2023.10.0-alpha-1/faf_windows-x64_2023_10_0-alpha-1.exe

If both options do not work, then check security settings and change your default browser just to narrow down the issue.
