Hi there! I understand you're having trouble with the Hotels.com app freezing right after you enter your login code, and it doesn't even display the full page with instructions. I’d like to help you get this sorted out.

To start, can you tell me if you've already tried any of these common steps? That way I can tailor my advice better:
- Restarting your phone
- Checking your internet connection (make sure it’s stable)
- Closing and reopening the app
- Updating the app to the latest version from the Play Store

If you haven’t tried those yet, let’s go through them quickly, since they fix many issues like freezing.

Assuming the basics are covered, here are some steps specific to your Android 10 device and the WebKit browser context:

1. Clear the app cache and data:
- Go to your phone’s Settings > Apps > Hotels.com
- Tap on Storage
- Choose Clear Cache first, then Clear Data
- Reopen the app and try logging in again

2. Try logging in on a different network, such as switching from Wi-Fi to mobile data or vice versa. Sometimes network issues or restrictions can cause freezes on the login page.

3. If the app still freezes, try uninstalling and reinstalling the Hotels.com app to ensure you have a fresh copy with no corrupted files.

4. Sometimes app freezes relate to CAPTCHA verification during login. If the page freezes after entering your code but before completing CAPTCHA, you can try logging in from the Hotels.com website using your device browser as a temporary workaround.

If you have already done all the above or are still stuck after trying these steps, it could be a more complex issue related to the app version compatibility with Android 10 or temporary server problems. In that case, I can check for any currently known outages or suggest contacting Hotels.com advanced support.

Would you please let me know which steps you have already tried? Then we can move forward with the best next solution.
