Cloudflare Turnstile showing Failure!

One of our site members is reporting the issue that the Cloudflare turnstile widget is showing failure hence she is unable to proceed further for Signin. She is facing this issue on Google Chrome with using Avast Premium Security in Windows 10. Cloudflare turnstile widget is working correctly on other browsers. She is just having the issue on her PC - her iPad works fine. On the coding side, we have checked the site key & secret key. Both are correct and working for us.
