I am present with the following error message. 

--> Smarty: Default handler: No template default content for 'file:templates/default/includes/captcha.tpl' <--

Hello,

Here, I am sharing some steps that you need to follow to fix the issue - 
1. Verify the File:
Check if the captcha.tpl file is present in the templates/default/includes/ directory of your WHMCS installation using FTP or your hosting control panel.

2. Restore or Upload:
If the file is missing, restore it from a backup or upload a fresh copy from another WHMCS installation that includes it.

3. Check Theme Compatibility:
After upgrading WHMCS or changing your theme, the new theme may lack the file. Revert to a previous theme or choose one that includes the necessary functionality.

If you're using a custom theme, you may need to create the missing captcha.tpl file or choose a theme that includes the required functionality.

Thanks

I'm using a child theme so the file should be picked up in the parent theme. I've tried two child themes and the same result. 
 

I've reverted to using Six and will review the changelog to see if there's anything obvious missing or needed.

Hi, you just need to copy templates/default/includes/captcha.tpl 
into your theme
templates/yourthemedirectory/includes/captcha.tpl 

This error will disappear, but your login issue is still there because the "Cross-Origin-Opener-Policy policy would block the window.postMessage call" 
You need to allow the Google Auth script to run. Or WHMCS needs to update the code to avoid using window.postMessage function

As you've noted I'm using a child theme so the file should be picked up in the parent theme. I've tried two child themes and the same result. Isn't the point of the child theme that you only include files that you want to overwrite?

Thank you for your post.

For this file, WHMCS does not get it from the parent theme. I don't know why but its happen. You can use a child theme, but your parent theme should be Six.  For example, if your child theme directory name is "mytheme" then just copy templates/default/includes/captcha.tpl into your theme templates/mytheme/includes/captcha.tpl 
make sure the path is correct meaning captcha.tpl should be in includes directory

Yes, the parent theme is Six. 

Can someone at WHMCS please provide input or a hotfix for this?
