welcome to the n8n community @Sourav_Paul
I’d first check the local npm/Windows setup rather than the Telegram token, because “missing ) after argument list” while creating any API credential usually points to a broken/outdated n8n install or incompatible Node.js version; update n8n, confirm you’re using a supported Node.js version, then restart n8n and try recreating the credential.
