Hi,
If you are using the Chinese language in your Overwolf settings, please could you change it to English? It might solve the issue.
Unfortunately, it makes no use.Maybe something goes wrong with the app.
Unfortunately we cannot accept API requests from mainland China as Riot’s official API does not support your region yet.
If you created your Valorant account outside of this region, but reside within China, please use a VPN until we can support your region.
Please note, some IPs used by proxy services may get blocked as they get detected as bots/ malicious users.
